IR4427S

Overview

25 V dual-channel low-side gate driver IC

EiceDRIVER™ 25 V dual-channel low-side gate driver IC with typical 2.3 A source and 3.3 A sink current in 8-lead SOIC and PDIP package for MOSFETs and IGBTs.

The proprietary latch immune CMOS technologies enable ruggedized monolithic construction. The logic inputs are compatible with standard CMOS or LSTTL output. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications.

Summary of Features

  • Wide supply voltage rage with 25 V VCC max
  • Gate drive supply range from 6 to 20V
  • CMOS Schmitt-triggered inputs
  • Matched propagation delay for both channels
  • Outputs in phase with inputs

Benefits

  • 25 V VCC max makes the IC more robust against VCC spikes in harsh circuit applications
  • Market proven
  • Industry standard package
