TC4421/TC4422

9A High-Speed MOSFET Drivers

Features

General Description

• High Peak Output Current: 9A

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

The TC4421/TC4422 are high-current buffer/drivers

capable of driving large MOSFETs and IGBTs.

These devices are essentially immune to any form of

upset, except direct overvoltage or over-dissipation.

They cannot be latched under any conditions within

their power and voltage ratings. These parts are not

subject to damage or improper operation when up to

5V of ground bounce is present on their ground termi-

nals. They can accept, without damage or logic upset,

more than 1A inductive current of either polarity being

forced back into their outputs. In addition, all terminals

are fully protected against up to 4 kV of electrostatic

discharge.

• High Continuous Output Current: 2A Max

• Fast Rise and Fall Times:

- 30 ns with 4,700 pF Load

- 180 ns with 47,000 pF Load

• Short Propagation Delays: 30 ns (typ)

• Low Supply Current:

- With Logic ‘1’ Input – 200 µA (typ)

- With Logic ‘0’ Input – 55 µA (typ)

• Low Output Impedance: 1.4Ω (typ)

The TC4421/TC4422 inputs may be driven directly

from either TTL or CMOS (3V to 18V). In addition,

300 mV of hysteresis is built into the input, providing

noise immunity and allowing the device to be driven

from slowly rising or falling waveforms.

• Latch-Up Protected: Will Withstand 1.5A Output

Reverse Current

• Input Will Withstand Negative Inputs Up To 5V

• Pin-Compatible with the TC4420/TC4429

6A MOSFET Driver

With both surface-mount and pin-through-hole

packages and four operating temperature range offer-

ings, the TC4421/22 family of 9A MOSFET drivers fit

into most any application where high gate/line

capacitance drive is required.

• Space-saving 8-Pin 6x5 DFN Package

Applications

• Line Drivers for Extra Heavily-Loaded Lines

• Pulse Generators

• Driving the Largest MOSFETs and IGBTs

• Local Power ON/OFF Switch

• Motor and Solenoid Driver
