IRS21271STRPBF 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 | VCC | power_in | Logic and gate drive supply, with a recommended operating range of 10 V to 20 V and an absolute maximum of 25 V. |
| 2 | IN | input | Logic input for gate driver output HO, in phase with HO for the IRS21271, with VIN limited to 0 V to VCC. |
| 3 | FAULT | output | Open-drain, negative-logic output that indicates an over-current shutdown has occurred. |
| 4 | COM | power_in | Logic ground, to which all voltage parameters are referenced. |
| 5 | VS | power_in | High-side floating supply return, rated for a high-side floating offset voltage up to 600 V. |
| 6 | CS | input | Current sense input to the current sense comparator, with a positive-going threshold of 1.8 V typical for the IRS21271. |
| 7 | HO | output | High-side gate drive output, swinging between VS and VB. |
| 8 | VB | power_in | High-side floating supply, rated at VS + 9 V to VS + 20 V for the IRS21271. |
