IR21271STRPBF-JSM from JSMSEMI, in a SOP-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 | Low-side supply voltage, rated -0.3 V to 22 V (recommended gate drive supply 8 V to 22 V) referenced to VSS. |
| 2 | IN | input | Logic input signal in phase with HO, compatible with 3.3 V, 5 V and 15 V logic, rated -0.3 V to VCC + 0.3 V. |
| 3 | FAULT | output | Active-low open-drain overcurrent shutdown fault report output, rated -0.3 V to VCC + 0.3 V. |
| 4 | VSS | power_in | Ground reference for the logic and supply voltages. |
| 5 | VS | power_in | High-side floating return, rated VB - 22 V to VB + 0.3 V with negative bias capability to -5 V. |
| 6 | CS | input | Overcurrent protection current-sense input, rated VS - 0.3 V to VB + 0.3 V. |
| 7 | HO | output | High-side gate driver output, rated VS - 0.3 V to VB + 0.3 V. |
| 8 | VB | power_in | High-side floating supply voltage, rated -0.3 V to 322 V maximum. |
