FAN3100 drivers incorporate millerdrive? architecture for the final output stage. this bipolar-mosfet combination provides high peak current during the miller plateau stage of the mosfet turn-on / turn-off process to minimize switching loss, while providing rail- to-rail voltage swing and reverse current capability. the FAN3100 also offers dual inputs that can be configured to operate in non-inverting or inverting mode and allow implementation of an enable function. if one or both inputs are left unconnec ted, internal resistors bias the inputs such that the output is pulled low to hold the power mosfet off. the FAN3100 is available in a lead-free finish 2x2mm 6-lead molded leadless package (mlp), for smallest size with excellent thermal performance, or industry- standard 5-pin sot23. functional pin configurations figure 1. 2x2mm 6-lead mlp (top view) figure 2. sot23-5 (top view)

? 2007 fairchild semiconductor corporation www.fairchildsemi.com FAN3100 ? rev. 1.0.1 14 FAN3100 ? single 2a high-speed, low-side gate driver applications information input thresholds the FAN3100 offers ttl or cmos input thresholds. in the FAN3100t, the input thresholds meet industry- standard ttl logic thresholds, independent of the v dd voltage, and there is a hysteresis voltage of approximately 0.4v. these levels permit the inputs to be driven from a range of input logic signal levels for which a voltage over 2v is considered logic high. the driving signal for the ttl inputs should have fast rising and falling edges with a slew rate of 6v/s or faster, so the rise time from 0 to 3.3v should be 550ns or less. with reduced slew rate, circuit noise could cause the driver input voltage to exceed the hysteresis voltage and retrigger the driver input, causing erratic operation. in the FAN3100c, the logic input thresholds are dependent on the v dd level and, with v dd of 12v, the logic rising edge threshold is approximately 55% of v dd and the input falling edge threshold is approximately 38% of v dd . the cmos input configuration offers a hysteresis voltage of approximately 17% of v dd . the cmos inputs can be used with relatively slow edges (approaching dc) if good decoupling and bypass techniques are incorporated in the system design to prevent noise from violating the input voltage hysteresis window. this allows setting precise timing intervals by fitting an r-c circuit between the controlling signal and the in pin of the driver. the slow rising edge at the in pin of the driver introduces a delay between the controlling signal and the out pin of the driver. static supply current in the i dd (static) typical performance graphs (figure 9 - figure 10 and figure 15 - figure 16), the curve is produced with all inputs floating (out is low) and indicates the lowest static i dd current for the tested configuration. for other states, additional current flows through the 100k resistors on the inputs and outputs shown in the block diagrams (see figure 5 - figure 6). in these cases, the actual static i dd current is the value obtained from the curves plus this additional current. millerdrive? gate drive technology FAN3100 drivers incorporate the millerdrive? architecture shown in figure 42 for the output stage, a combination of bipolar and mos devices capable of providing large currents over a wide range of supply voltage and temperature variations. the bipolar devices carry the bulk of the current as out swings between 1/3 to 2/3 v dd and the mos devices pull the output to the high or low rail. the purpose of the millerdrive? architecture is to speed up switching by providing the highest current during the miller plateau region when the gate-drain capacitance of the mosfet is being charged or discharged as part of the turn-on / turn-off process. for applications that have zero voltage switching during the mosfet turn-on or turn-off interval, the driver supplies high peak current for fast switching even though the miller plateau is not present. this situation often occurs in synchronous rectifier applications because the body diode is generally conducting before the mosfet is switched on. the output pin slew rate is determined by v dd voltage and the load on the output. it is not user adjustable, but if a slower rise or fall time at the mosfet gate is needed, a series resistor can be added. figure 42. millerdrive? output architecture under-voltage lockout the FAN3100 start-up logic is optimized to drive ground referenced n-channel mosfets with a under-voltage lockout (uvlo) function to ensure that the ic starts up in an orderly fashion. when v dd is rising, yet below the 3.9v operational level, this circuit holds the output low, regardless of the status of t he input pins. after the part is active, the supply voltage must drop 0.2v before the part shuts down. this hysteresis helps prevent chatter when low v dd supply voltages have noise from the power switching. this configuration is not suitable for driving high-side p-channel mosfets because the low output voltage of the driver would turn the p-channel mosfet on with v dd below 3.9v. vdd bypass capacitor guidelines to enable this ic to turn a power device on quickly, a local, high-frequency, bypass capacitor c byp with low esr and esl should be connected between the vdd and gnd pins with minimal trace length. this capacitor is in addition to bulk electrolytic capacitance of 10f to 47f often found on driver and controller bias circuits. a typical criterion for choosing the value of c byp is to keep the ripple voltage on the v dd supply 5%. often this is achieved with a value 20 times the equivalent load capacitance c eqv , defined here as q gate /v dd . ceramic capacitors of 0.1f to 1f or larger are common choices, as are dielectrics, such as x5r and x7r, which have good temperature characteristics and high pulse current capability. if circuit noise affects normal operation, the value of c byp may be increased to 50-100 times the c eqv , or c byp may be split into two capacitors. one should be a larger value, based on equivalent load capacitance, and the other a smaller value, such as 1-10nf, mounted closest to the vdd and gnd pins to carry the higher- frequency components of the current pulses.
? 2007 fairchild semiconductor corporation www.fairchildsemi.com FAN3100 ? rev. 1.0.1 15 FAN3100 ? single 2a high-speed, low-side gate driver layout and connection guidelines the FAN3100 incorporates fast reacting input circuits, short propagation delays, and powerful output stages capable of delivering current peaks over 2a to facilitate voltage transition times from under 10ns to over 100ns. the following layout and connection guidelines are strongly recommended: ? keep high-current output and power ground paths separate from logic input signals and signal ground paths. this is especially critical when dealing with ttl-level logic thresholds. ? keep the driver as close to the load as possible to minimize the length of high-current traces. this reduces the series inductance to improve high- speed switching, while reducing the loop area that can radiate emi to the driver inputs and other surrounding circuitry. ? the FAN3100 is available in two packages with slightly different pinouts, offering similar performance. in the 6-pin mlp package, pin 2 is internally connected to the input analog ground and should be connected to power ground, pin 5, through a short direct path underneath the ic. in the 5-pin sot23, the internal analog and power ground connections are made through separate, individual bond wires to pin 2, which should be used as the common ground point for power and control signals. ? many high-speed power circuits can be susceptible to noise injected from their own output or other external sources, possibly causing output re- triggering. these effects can be especially obvious if the circuit is tested in breadboard or non-optimal circuit layouts with long input, enable, or output leads. for best results, make connections to all pins as short and direct as possible. ? the turn-on and turn-off current paths should be minimized as discussed in the following sections. figure 43 shows the pulsed gate drive current path when the gate driver is supplying gate charge to turn the mosfet on. the current is supplied from the local bypass capacitor, c byp , and flows through the driver to the mosfet gate and to ground. to reach the high peak currents possible, the resistance and inductance in the path should be minimized. the localized c byp acts to contain the high peak current pulses within this driver-mosfet circuit, preventing them from disturbing the sensitive analog circuitry in the pwm controller. figure 43. current path for mosfet turn-on figure 44 shows the current path when the gate driver turns the mosfet off. ideally, the driver shunts the current directly to the source of the mosfet in a small circuit loop. for fast turn-off times, the resistance and inductance in this path should be minimized. figure 44. current path for mosfet turn-off truth table of logic operation the FAN3100 truth table indicates the operational states using the dual-input configuration. in a non- inverting driver configuration, the in- pin should be a logic low signal. if the in- pin is connected to logic high, a disable function is realized, and the driver output remains low regardless of the state of the in+ pin. in+ in- out 0 0 0 0 1 0 1 0 1 1 1 0 in the non-inverting driver configuration in figure 45, the in- pin is tied to ground and the input signal (pwm) is applied to in+ pin. the in- pin can be connected to logic high to disable the driver and the output remains low, regardless of the state of the in+ pin. figure 45. dual-input driver enabled, non-inverting configuration in the inverting driver application shown in figure 46, the in+ pin is tied high. pulling the in+ pin to gnd forces the output low, regardless of the state of the in- pin. figure 46. dual-input driver enabled, inverting configuration
? 2007 fairchild semiconductor corporation www.fairchildsemi.com FAN3100 ? rev. 1.0.1 16 FAN3100 ? single 2a high-speed, low-side gate driver operational waveforms at power up, the driver output remains low until the v dd voltage reaches the turn-on threshold. the magnitude of the out pulses rises with v dd until steady-state v dd is reached. the non-inverting operation illustrated in figure 47 shows that the output remains low until the uvlo threshold is reached, then the output is in-phase with the input. figure 47. non-inverting start-up waveforms for the inverting configuration of figure 46, start-up waveforms are shown in figure 48. with in+ tied to vdd and the input signal applied to in?, the out pulses are inverted with respect to the input. at power up, the inverted output remains low until the v dd voltage reaches the turn-on threshold, then it follows the input with inverted phase. figure 48. inverting start-up waveforms thermal guidelines gate drivers used to switch mosfets and igbts at high frequencies can dissipate significant amounts of power. it is important to determine the driver power dissipation and the resulting junction temperature in the application to ensure that the part is operating within acceptable temperature limits. the total power dissipation in a gate driver is the sum of two components; p gate and p dynamic : p total = p gate + p dynamic (1) gate driving loss: the most significant power loss results from supplying gate current (charge per unit time) to switch the load mosfet on and off at the switching frequency. the power dissipation that results from driving a mosfet at a specified gate- source voltage, v gs , with gate charge, q g , at switching frequency, f sw , is determined by: p gate = q g ? v gs ? f sw (2) dynamic pre-drive / shoot-through current: a power loss resulting from internal current consumption under dynamic operating conditions, including pin pull-up / pull-down resistors, can be obtained using the i dd (no-load) vs. frequency graphs in typical performance characteristics to determine the current i dynamic drawn from v dd under actual operating conditions: p dynamic = i dynamic ? v dd (3) once the power dissipated in the driver is determined, the driver junction rise with respect to circuit board can be evaluated using the following thermal equation, assuming jb was determined for a similar thermal design (heat sinking and air flow): t j = p total ? jb + t b (4) where: t j = driver junction temperature jb = (psi) thermal characterization parameter relating temperature rise to total power dissipation t b = board temperature in location defined in the thermal characteristics table. in a typical forward converter application with 48v input, as shown in figure 49, the fds2672 would be a potential mosfet selection. the typical gate charge would be 32nc with v gs = v dd = 10v. using a ttl input driver at a switching frequency of 500khz, the total power dissipation can be calculated as: p gate = 32nc ? 10v ? 500khz = 0.160w (5) p dynamic = 8ma ? 10v = 0.080w (6) p total = 0.24w (7) the 5-pin sot23 has a junction-to-lead thermal characterization parameter jb = 51c/w. in a system application, the localized temperature around the device is a function of the layout and construction of the pcb along with airflow across the surfaces. to ensure reliable operation, the maximum junction temperature of the device must be prevented from exceeding the maximum rating of 150c; with 80% derating, t j would be limited to 120c. rearranging equation 4 determines the board temperature required to maintain the junction temperature below 120c: t b,max = t j - p total ? jb (8) t b,max = 120c ? 0.24w ? 51c/w = 108c (9) for comparison purposes, replace the 5-pin sot23 used in the previous example with the 6-pin mlp package with jb = 2.8c/w. the 6-pin mlp package can operate at a pcb temperature of 119c, while maintaining the junction temperature below 120c. this illustrates that the physically smaller mlp package with thermal pad offers a more conductive path to remove the heat from the driver. consider the tradeoffs between reducing overall circuit size with junction temperature reduction for increased reliability.
