IR4427STRPBF

Infineon Technologies · Gate Drivers · SOIC-8

IR4427STRPBF 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 connect; pin 1 is shown as NC in the typical connection diagram and has no function in the lead definitions.
2 INA input Logic input for gate driver output OUTA, in phase for IR4427, with CMOS Schmitt-triggered input, VIH min 2.7V, VIL max 0.8V, and range -0.3V to VS+0.3V.
3 GND power_in Ground reference for all voltages.
4 INB input Logic input for gate driver output OUTB, in phase for IR4427, with CMOS Schmitt-triggered input, VIH min 2.7V, VIL max 0.8V, and range -0.3V to VS+0.3V.
5 OUTB output Gate drive output B with 1.5A source and 1.5A sink minimum pulsed short-circuit current, swinging 0 to VS.
6 VS power_in Supply voltage, recommended 6V to 20V, absolute maximum 25V.
7 OUTA output Gate drive output A with 1.5A source and 1.5A sink minimum pulsed short-circuit current, swinging 0 to VS.
8 NC unconnected No connect; pin 8 is shown as NC in the typical connection diagram and has no function in the lead definitions.
