Fig.6 Application diagram. Introduction (see Fig.7) Full-wave driving of a three phase motor requires three push-pull output stages. In each of the six possible states two outputs are active, one sourcing (H) and one sinking (L). The third output presents a high impedance (Z) to the motor, which enables measurement of the motor back EMF in the corresponding motor coil by the EMF comparator at each output. The commutation logic is responsible for control of the output transistors and selection of the correct EMF comparator. The sequence of the six possible states of the outputs is given in Table 1. The zero-crossing in the motor EMF (detected by the comparator selected by the commutation logic) is used to calculate the correct moment for the next commutation, that is, the change to the next output state. The delay is calculated (depending on the motor loading) by the adaptive commutation delay block. Because of high inductive loading the output stages contain flyback diodes. The output stages are also protected by a current limiting circuit and by thermal protection of the six output transistors. Table 1 Output states; note 1 STATE 1 2 3 4 5 6 Note 1. H = HIGH state; L = LOW state; Z = high-impedance OFF-state. The system will only function when the EMF voltage from the motor is present. Therefore, a start oscillator is provided that will generate commutation pulses when no zero-crossings in the motor voltage are available. A timing function is incorporated into the device for internal timing and for timing of the reverse rotation detection. MOT1 Z H H Z L L MOT2 L L Z H H Z MOT3 H Z L L Z H 1998 Oct 27 9 Philips Semiconductors Product specification Brushless DC motor drive circuit The TDA5145TS is designed for systems with low current consumption: use of I2L logic, adaptive base drive for the output transistors (patented). Adjustments The system has been designed in such a way that the tolerances of the application components are not critical. However, the approximate values of the following components must still be determined: * The start capacitor; this determines the frequency of the start oscillator. * The two capacitors in the adaptive commutation delay circuit; these are important in determining the optimum moment for commutation, depending on the type and loading of the motor. * The timing capacitor; this provides the system with its timing signals. THE START CAPACITOR (CAP-ST) This capacitor determines the frequency of the start oscillator. It is charged and discharged, with a current of 2 A, from 0.05 to 2.2 V and back to 0.05 V. The time taken to complete one cycle is given by: tstart = (2.15 x C) s (with C in F) The start oscillator is reset by a commutation pulse and so is only active when the system is in the start-up mode. A pulse from the start oscillator will cause the outputs to change to the next state (torque in the motor). If the movement of the motor generates enough EMF the TDA5145TS will run the motor. If the amount of EMF generated is insufficient, then the motor will move one step only and will oscillate in its new position. The amplitude of the oscillation must decrease sufficiently before the arrival of the next start pulse, to prevent the pulse arriving during the wrong phase of the oscillation. The oscillation of the motor is given by: 1 f osc = ---------------------------------Kt x I x p 2 ---------------------J where: Kt = torque constant (N.m/A) I = current (A) p = number of magnetic pole-pairs J = inertia J (kg.m2) Example: J = 72 x 10-6 kg.m2, Kt = 25 x 10-3 N.m/A, p = 6 and I = 0.5 A; this gives fosc = 5 Hz. TDA5145TS If the damping is high then a start frequency of 2 Hz can be chosen or t = 500 ms, thus C = 0.5/2 = 0.25 F (choose 220 nF). THE ADAPTIVE COMMUTATION DELAY (CAP-CD AND CAP-DC) In this circuit, capacitor CAP-CD is charged during one commutation period, with an interruption of the charging current during the diode pulse. During the next commutation period this capacitor (CAP-CD) is discharged at twice the charging current. The charging current is 8.1 A and the discharging current 16.2 A; the voltage range is from 0.9 to 2.2 V. The voltage must stay within this range at the lowest commutation frequency of interest, fC1: 6231 8.1 x 10 C = ------------------------- = ------------ (C in nF) f C1 f x 1.3 If the frequency is lower, then a constant commutation delay after the zero-crossing is generated by the discharge from 2.2 to 0.9 V at 16.2 A; maximum delay = (0.076 x C) ms (with C in nF) Example: nominal commutation frequency = 900 Hz and the lowest usable frequency = 400 Hz; thus: 6231 CAP-CD = ------------ = 15.6 (choose 18 nF) 400 The other capacitor, CAP-DC, is used to repeat the same delay by charging and discharging with 15.5 A. The same value can be chosen as for CAP-CD.

THE TIMING CAPACITOR (CAP-TI) Capacitor CAP-TI is used for timing the successive steps within one commutation period; these steps include some internal delays. The most important function is the watchdog time in which the motor EMF has to recover from a negative diode pulse back to a positive EMF voltage (or vice versa). A watchdog timer is a guarding function that only becomes active when the expected event does not occur within a predetermined time. The EMF usually recovers within a short time if the motor is running normally (< The capacitor is charged with a current of 57 A, from 0.2 to 0.3 V. Above this level it is charged with a current of 5 A, up to 2.2 V only if the selected motor EMF remains in the wrong polarity (watchdog function). At the end, or, if the motor voltage becomes positive, the capacitor is discharged with a current of 28 A. The watchdog time is the time taken to charge the capacitor with a current of 5 A, from 0.3 to 2.2 V. To ensure that the internal delays are covered CAP-TI must have a minimum value of 2 nF. For the watchdog function a value of 10 nF for CAP-TI is recommended. To ensure a good start-up and commutation, care must be taken that no oscillations occur at the trailing edge of the flyback pulse. Snubber networks at the outputs should be critically damped. Typical voltage waveforms are illustrated in Fig.9. 1998 Oct 27 12 Philips Semiconductors Product specification Brushless DC motor drive circuit TDA5145TS handbook, full pagewidth VMOT 1 voltage on CAP-TI MGH318 If the chosen value of CAP-TI is too small oscillations can occur in certain positions of a blocked rotor. If the chosen value is too large, then it is possible that the motor may run in the reverse direction (synchronously with little torque). Fig.9 Typical CAP-TI and VMOT1 voltage waveforms in normal running mode. Other design aspects There are other design aspects concerning the application of the TDA5145TS besides the commutation function. They are: * Direction function * Brake function * Reliability. DIRECTION FUNCTION If the voltage at pin 9 is less than 0.8 V, the motor is running in one direction (depending on the motor connections). If the voltage at pin 9 is greater than 2.0 V, the motor is running in the opposite direction. BRAKE FUNCTION If the voltage at pin 8 is greater than 2.0 V, the motor brakes. In that condition, the 3 outputs MOT1, MOT2 and MOT3 are forced to a LOW voltage level and the current limitation is performed internally by the sink drivers. RESET FUNCTION If the voltage at pin 18 is greater than 2.0 V, the output states are shown in Table 2. Table 2 Output states if VRESET > 2.0 V STATE(1) Z L H DRIVER OUTPUT MOT1 MOT2 MOT3 Note 1.

The `upper' output transistors use the same base current as the conducting `lower' transistor (+15%). This means that the current to and from the output stages is limited. * Thermal protection of the six output transistors is achieved by each transistor having a thermal sensor that is active when the transistor is switched on. The transistors are switched off when the ambient temperature becomes too high. 1998 Oct 27 14 Philips Semiconductors Product specification Brushless DC motor drive circuit PACKAGE OUTLINE SSOP24: plastic shrink small outline package; 24 leads; body width 5.3 mm TDA5145TS SOT340-1 D E A X c y HE vMA Z 24 13 Q A2 pin 1 index A1 (A 3) Lp L 1 e bp 12 wM detail X A 0 2.5 scale 5 mm DIMENSIONS (mm are the original dimensions) UNIT mm A max. 2.0 A1 0.21 0.05 A2 1.80 1.65 A3 0.25 bp 0.38 0.25 c 0.20 0.09 D (1) 8.4 8.0 E (1) 5.4 5.2 e 0.65 HE 7.9 7.6 L 1.25 Lp 1.03 0.63 Q 0.9 0.7 v 0.2 w 0.13 y 0.1 Z (1) 0.8 0.4 8 0o o Note 1.

Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all SSOP packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering Wave soldering is not recommended for SSOP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. TDA5145TS If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow and must incorporate solder thieves at the downstream end. Even with these conditions, only consider wave soldering SSOP packages that have a body width of 4.4 mm, that is SSOP16 (SOT369-1) or SSOP20 (SOT266-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 1998 Oct 27 16 Philips Semiconductors Product specification Brushless DC motor drive circuit DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values TDA5145TS This data sheet contains target or goal specifications for product development.
