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. |
