Product Description
6A Non-Inverting High-Speed MOSFET DriverDescriptionThe TC4420/TC4429 are 6A (peak), single-output MOSFET drivers.
The TC4429 is an inverting driver (pin-compatible with the TC429), while the TC4420 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 that 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.
Propagational delay time is only 55 ns (typ.
) and the output rise and fall times are only 25 ns (typ.
) into 2500 pF across the usable power supply range.
Unlike other drivers, the TC4420/TC4429 are virtually latch-up proof.
They replace three or more discrete components, saving PCB area, parts and improving overall system reliability.
