General Description

The TC4421A/TC4422A are improved versions of the

earlier TC4421/TC4422 family of single-output

MOSFET drivers. These devices are high-current buf-

fer/drivers capable of driving large MOSFETs and Insu-

lated 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.

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.

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.

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.
