Description

The IR21303C is a high voltage, high speed power MOSFET and IGBT driver with three independent high and

low side referenced output channels. Proprietary HVIC technology enables ruggedized monolithic construction.

Logic inputs are compatible with CMOS or LSTTL outputs, down to 2.5V logic. A ground-referenced opera-

tional amplifier provides analog feedback of bridge current via an external current sense resistor. A current trip

function which terminates all six outputs is also derived from this resistor. An open drain FAULT signal

indicates if an over-current or undervoltage shutdown has occurred. The output drivers feature a high pulse

current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify

use at high frequencies. The floating channels can be used to drive N-channel power MOSFETs or IGBTs in

the high side configuration which operate up to 600 volts.
