The TC4422 is a 9A non-inverting high-speed MOSFET driver designed for driving large MOSFETs and IGBTs. It operates from a 4.5V to 18V supply, delivers a continuous output current of 2A, and provides peak output current of 9A. The device features a 30ns typical propagation delay, rise and fall times of 30ns with a 4,700pF load, and low output impedance of 1.4Ω. It is available in an 8-pin 6x5 DFN-S package with an exposed thermal pad, includes 300mV input hysteresis for noise immunity, and accepts TTL or CMOS inputs from 3V to 18V. All terminals are protected against 4kV electrostatic discharge, and the device is latch-up protected against 1.5A reverse current. It meets operating temperature ranges of 0°C to +70°C, -40°C to +85°C, and -40°C to +125°C.
The TC4421/4422 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 TC4421/4422 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.
