IRS4426/IRS4427/IRS4428(S)PbF
Features
Gate drive supply range from 6 V to 20 V
CMOS Schmitt-triggered inputs
Matched propagation delay for both channels
Outputs out of phase with inputs (IRS4426)
Outputs in phase with inputs (IRS4427)
OutputA out of phase with inputA and

RoHS compliant
Descriptions
The IRS4426/IRS4427/IRS4428 are low voltage,
high speed power MOSFET and IGBT driver. Pro-
prietary latch immune CMOS technologies en-
able rugged ized mono lithic construction. Logic
inputs are compatible with standard CMOS or
LSTTL outputs. The output drivers feature a high
pu lse curren t buffer stage de signed for mini-
mum driver cross-condu ction . Propaga tion
de lays be tween two channels are matched.
