General Description

• Driving the Largest MOSFETs and IGBTs

• Local Power ON/OFF Switch

• Motor and Solenoid Driver

The TC4421/TC4422 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; they 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 either 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 4kV of electrostatic discharge.

The TC4421/TC4422 inputs may be driven directly

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

300mV of hysteresis is built into the input, providing

noise immunity and allowing the device to be driven

from slowly rising or falling waveforms.
