IRS4426STRPBF

Infineon Technologies · Gate Drive ICs · SOIC-8

IRS4426STRPBF from Infineon Technologies, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection; this pin is not connected internally.
2 INA input Logic input for gate driver output OUTA, out of phase with the output for IRS4426 and IRS4428 and in phase for IRS4427.
3 GND power_in Ground reference for the device, to which all voltages are referenced (COM).
4 INB input Logic input for gate driver output OUTB, out of phase for IRS4426 and in phase for IRS4427 and IRS4428.
5 OUTB output Gate drive output B.
6 VCC power_in Supply voltage; the recommended gate drive supply range is 6 V to 20 V.
7 OUTA output Gate drive output A.
8 NC unconnected No connection; this pin is not connected internally.
