TC4421M/TC4422M

9A High-Speed MOSFET Drivers

General Description

Features

• High Peak Output Current: 9A

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

The TC4421M/TC4422M are high-current buffer/

drivers capable of driving large MOSFETs and IGBTs.

They 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.

• 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)

• Latch-Up Protected: Will Withstand 1.5A Output

Reverse Current

The TC4421M/TC4422M 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.

• Input: Will Withstand Negative Inputs Up To 5V

• Pin-Compatible with the TC4420M/TC4429M

6A MOSFET Driver

Package Types

• Wide Operating Temperature Range:

- -55°C to +125°C
