General Description
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. 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.

3.1
Supply Input (VDD)
3.3
CMOS Push-Pull Output
The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 18V with respect to the ground pin. The VDD input should be bypassed to ground with a local ceramic capacitor. The value of the capacitor should be chosen based on the capacitive load that is being driven. A minimum value of 1.0 F is suggested.
The MOSFET driver output is a low-impedance, CMOS, push-pull style output capable of driving a capacitive load with 9.0A peak currents. The MOSFET driver output is capable of withstanding 1.5A peak reverse currents of either polarity.
3.4 3.2 Control Input
The MOSFET driver input is a high-impedance, TTL/CMOS-compatible input. The input also has 300 mV of hysteresis between the high and low thresholds that prevents output glitching even when the rise and fall time of the input signal is very slow.
Ground
The ground pins are the return path for the bias current and for the high peak currents that discharge the load capacitor. The ground pins should be tied into a ground plane or have very short traces to the bias supply source return.
