IRS4428STRPBF 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 | Pin 1 is not connected internally and is listed as No connection in the lead definitions. |
| 2 | INA | input | Logic input for gate driver output OUTA, which is out of phase with the input on the IRS4428. |
| 3 | GND | power_in | Ground reference for the device, to which all voltages are referenced. |
| 4 | INB | input | Logic input for gate driver output OUTB, which is in phase with the input on the IRS4428. |
| 5 | OUTB | output | Gate drive output B of the second independent low side driver channel. |
| 6 | VCC | power_in | Supply voltage for the gate drivers, rated 6 V to 20 V in the recommended operating conditions. |
| 7 | OUTA | output | Gate drive output A of the first independent low side driver channel. |
| 8 | NC | unconnected | Pin 8 is not connected internally and is listed as No connection in the lead definitions. |
