Overview
NCP4420, NCP4429 6 A High-Speed MOSFET Drivers The NCP4420/NCP4429 are 6 A (peak), single output, MOSFET drivers.
The NCP4429 is an inverting driver while the NCP4420 is a non–inverting driver.
These drivers are fabricated in CMOS for lower power and more efficient operation versus bipolar drivers.
Both drivers have TTL–compatible inputs, which can be driven as high as VDD + 0.
3 V or as low as –5 V 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 nsec (typ.
) and the output rise and fall times are only 25 nsec (typ.
) into 2500 pF across the useable power supply range.
Unlike other drivers, the NCP4420/NCP4429 are virtually latch–up proof.
They can replace three or more discrete components saving PCB area, costs and improving overall system reliability.
