Applications • Switch-mode Power Supplies • Motor Controls • Pulse Transformer Driver • Class D Switching Amplifiers General Description The TC4420M/TC4429M are 6A (peak), single-output MOSFET drivers. The TC4429M is an inverting driver (pin-compatible with the TC429M), while the TC4420M is a non-inverting driver. These drivers are fabricated in CMOS for lower power and more efficient operation versus bipolar drivers. Both devices have TTL/CMOS-compatible inputs, which can be driven as high as VDD + 0.3V or as low as -5V without upset or damage to the device. This eliminates the need for external level-shifting circuitry and its associated cost and size. The output swing is rail-to-rail, ensuring better drive voltage margin, especially during power-up/power-down sequencing. The propagational delay time is only 55 ns (typ.), while the output rise and fall times are only 25 ns (typ.) into 2500 pF across the usable power supply range. Unlike other drivers, the TC4420M/TC4429M are virtually latch-up proof. They replace three or more discrete components, saving PCB area and parts while improving overall system reliability.
