General Description
The TC429 is a high-speed, single output, CMOS-level translator and driver. Designed specifically to drive highly capacitive power MOSFET gates, the TC429 features a 2.5Ω output impedance and 6A peak output current drive.
A 2500 pF capacitive load will be driven to 18V in 25 nsec. The rapid switching times with large capacitive loads minimize MOSFET switching power losses.
A TTL/CMOS input logic level is translated into an output voltage swing that equals the supply voltage and will swing to within 25 mV of ground or VDD. Input voltage swing may equal the supply voltage. Logic input current is under 10 µA, making direct interface to CMOS/bipolar switch-mode power supply controllers easy. Input “speed-up” capacitors are not required.
The CMOS design minimizes quiescent power supply current. With a logic ‘1’ input, power supply current is 5 mA maximum and decreases to 0.5 mA for logic ‘0’ inputs.
For dual output MOSFET drivers, see the TC426/TC427/TC428 (DS21415), TC4426/TC4427/TC4428 (DS21422) and TC4426A/TC4427A/TC4428A (DS21423) data sheets.
For non-inverting applications, or applications requiring latch-up protection, see the TC4420/TC4429 (DS21419) data sheet.
