IRS21867STR from UMW, 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 and logic fixed supply, recommended 6.8 V to 20 V with an absolute maximum of 25 V referenced to COM. |
| 2 | HIN | input | Logic input for the high side gate driver output (HO), in phase; compatible with 3.3 V, 5 V and 15 V logic, with VIH of 2.5 V minimum and VIL of 0.8 V maximum. |
| 3 | LIN | input | Logic input for the low side gate driver output (LO), in phase; compatible with 3.3 V, 5 V and 15 V logic, with VIH of 2.5 V minimum and VIL of 0.8 V maximum. |
| 4 | COM | power_in | Low side return; all voltage ratings are referenced to COM. |
| 5 | LO | output | Low side gate drive output, swinging between 0 V and VCC, with typical source/sink capability of 4 A. |
| 6 | VS | power_in | High side floating supply return, recommended range -9 V to 700 V; allowable negative Vs capability is -9 V. |
| 7 | HO | output | High side gate drive output, referenced to VS and swinging between VS and VB, with typical source/sink capability of 4 A. |
| 8 | VB | power_in | High side floating supply, recommended VS + 10 V to VS + 20 V with an absolute maximum of 725 V referenced to COM. |
