  • TC4420 6A MOSFET Gate Driver
  • The TC4420 is 6 A (peak),single output MOSFET gate driver.
  • TC4420 is a non-inverting driver. These drivers are fabricated in CMOS for lower power, more efficient operation versus bipolar drivers. Both devices 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 ns (typical) and the output rise and fall times are only 25 ns (typical) into 2,500 pF across the usable power supply range. Unlike other drivers, the TC4420/4429 are virtually latch-up proof. They replace three or more discrete components saving PCB area, parts and improving overall system reliability.
