IRS4426/IRS4427/IRS4428(S)PbF DUAL LOW SIDE DRIVER
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
outputB in phase with inputB (IRS4428) RoHS compliant
Product Summary
IO+/VOUT ton/off (typ.)
1.5 A / 1.5 A 6 V - 20 V 50 ns & 50 ns
Descriptions
The IRS4426/IRS4427/IRS4428 are low
voltage, high speed power
MOSFET and IGBT driver. Proprietary latch immune
CMOS technologies enable 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 minimum driver cross-condu ction . Propaga tion de lays be tween two channels are matched.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute
voltages referenced to GND. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
