A TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25 mV of ground or positive supply. The low-impedance, high-current driver outputs swing a 1000 pF load 18V in 30 nsec. The unique current and voltage drive qualities make the TC426/TC427/TC428 ideal power MOSFET drivers, line drivers, and DC-toDC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1 A, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators. Quiescent power supply current is 8 mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications. Quiescent current is typically 6 mA when driving a 1000 pF load 18V at 100 kHz. The inverting TC426 driver is pin-compatible with the bipolar DS0026 and MMH0026 devices. The TC427 is noninverting; the TC428 contains an inverting and noninverting driver. Other pin compatible driver families are the TC1426/ TC1427/TC1428, TC4426/TC4427/TC4428 and TC4426A/TC4427A/TC4428A.

DS21415C-page 5 TC426/TC427/TC428 3.0 3.1 APPLICATIONS INFORMATION Supply Bypassing 3.4 Power Dissipation Charging and discharging large capacitive loads quickly requires large currents. For example, charging a 1000 pF load to 18V in 25 nsec requires an 0.72A current from the device power supply. To ensure low supply impedance over a wide frequency range, a parallel capacitor combination is recommended for supply bypassing. Low-inductance ceramic disk capacitors with short lead lengths (< 0.5 in.) should be used. A 1 F film capacitor in parallel with one or two 0.1 F ceramic disk capacitors normally provides adequate bypassing. The supply current vs frequency and supply current vs capacitive load characteristic curves will aid in determining power dissipation calculations. The TC426/TC427/TC428 CMOS drivers have greatly reduced quiescent DC power consumption. Maximum quiescent current is 8 mA compared to the DS0026 40 mA specification. For a 15V supply, power dissipation is typically 40 mW. Two other power dissipation components are: * Output stage AC and DC load power. * Transition state power. Output stage power is: Po = PDC + PAC = Vo (IDC) + f CL VS2 Where: Vo IDC f Vs = DC output voltage = DC output load current = Switching frequency = Supply voltage 3.2 Grounding The TC426 and TC428 contain inverting drivers. Ground potential drops developed in common ground impedances from input to output will appear as negative feedback and degrade switching speed characteristics. Individual ground returns for the input and output circuits or a ground plane should be used. 3.3 Input Stage The input voltage level changes the no-load or quiescent supply current. The N-channel MOSFET input stage transistor drives a 2.5 mA current source load. With a logic `1' input, the maximum quiescent supply current is 8 mA. Logic `0' input level signals reduce quiescent current to 0.4 mA maximum. Minimum power dissipation occurs for logic `0' inputs for the TC426/TC427/TC428. Unused driver inputs must be connected to VDD or GND. The drivers are designed with 100 mV of hysteresis. This provides clean transitions and minimizes output stage current spiking when changing states. Input voltage thresholds are approximately 1.5V, making the device TTL compatible over the 4.5V to 18V supply operating range. Input current is less than 1 A over this range. The TC426/TC427/TC428 may be directly driven by the TL494, SG1526/1527, SG1524, SE5560, and similar switch-mode power supply integrated circuits. In power MOSFET drive applications the PDC term is negligible. MOSFET power transistors are high-impedance, capacitive input devices. In applications where resistive loads or relays are driven, the PDC component will normally dominate. The magnitude of PAC is readily estimated for several cases: A. 1. f 2. CL 3. Vs 4. PAC = 200 kHZ =1000 pf = 18V = 65 mW B. 1. f 2. CL 3. Vs 4. PAC = 200 kHz =1000 pf = 15V = 45 mW During output level state changes, a current surge will flow through the series connected N and P channel output MOSFETS as one device is turning "ON" while the other is turning "OFF". The current spike flows only during output transitions. The input levels should not be maintained between the logic `0' and logic `1' levels. Unused driver inputs must be tied to ground and not be allowed to float. Average power dissipation will be reduced by minimizing input rise times. As shown in the characteristic curves, average supply current is frequency dependent. DS21415C-page 6 (c) 2006 Microchip Technology Inc.
