IR4426/IR4427/IR4428(S) & (PbF)
Features
• Gate drive supply range from 6 to 20V
• CMOS Schmitt-triggered inputs
• Matched propagation delay for both channels
• Outputs out of phase with inputs (IR4426)
• Outputs in phase with inputs (IR4427)
• OutputA out of phase with inputA and
OutputB in phase with inputB (IR4428)
• Also available LEAD-FREE
Descriptions
The IR4426/IR4427/IR4428 (S) is a low voltage,
high speed power MOSFET and IGBT driver. Pro-
prietary latch immune CMOS technologies en-
able 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 mini-
mum driver cross-conduction. Propagation
delays between two channels are matched.
