TC4421A/TC4422A

9A High-Speed MOSFET Drivers

General Description

Features

• High Peak Output Current: 10A (typ.)

The TC4421A/TC4422A are improved versions of the

earlier TC4421/TC4422 family of single-output

MOSFET drivers. These devices are high-current

buffer/drivers capable of driving large MOSFETs and

Insulated Gate Bipolar Transistors (IGBTs). The

TC4421A/TC4422A have matched output rise and fall

times, as well as matched leading and falling-edge

propagation delay times. The TC4421A/TC4422A

devices also have very low cross-conduction current,

reducing the overall power dissipation of the device.

• Low Shoot-Through/Cross-Conduction Current in

Output Stage

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

• High Continuous Output Current: 2A (max.)

• Matched Fast Rise and Fall Times:

- 15 ns with 4,700 pF Load

- 135 ns with 47,000 pF Load

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

terminals. 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.

• Matched Short Propagation Delays: 42 ns (typ.)

• Low Supply Current:

- With Logic ‘1’ Input – 130 µA (typ.)

- With Logic ‘0’ Input – 33 µA (typ.)

• Low Output Impedance: 1.2Ω (typ.)

• Latch-Up Protected: Will Withstand 1.5A Output

Reverse Current

• Input Will Withstand Negative Inputs Up To 5V

• Pin-Compatible with the TC4420/TC4429

and TC4421/TC4422 MOSFET Drivers

The TC4421A/TC4422A 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.

• Space-Saving, Thermally-Enhanced, 8-Pin DFN

Package

Applications

• Line Drivers for Extra Heavily-Loaded Lines

• Pulse Generators

With both surface-mount and pin-through-hole

packages, in addition to a wide operating temperature

range, the TC4421A/TC4422A family of 9A MOSFET

drivers fit into most any application where high gate/line

capacitance drive is required.

• Driving the Largest MOSFETs and IGBTs

• Local Power ON/OFF Switch

• Motor and Solenoid Driver

• LF Initiator
