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 ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays between two channels are matched.
