IRS2104STR 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 operating range 10 V to 20 V, absolute maximum -0.3 V to 25 V. |
| 2 | IN | input | Logic input for high side and low side gate driver outputs, in phase with HO, compatible with 3.3 V, 5 V and 15 V logic with VIH minimum 2.5 V and VIL maximum 0.8 V. |
| 3 | SD | input | Logic input for shutdown, which turns off both channels, with input range 0 V to VCC. |
| 4 | VSS | power_in | Low side return and reference for all voltage ratings in the datasheet. |
| 5 | LO | output | Low side gate drive output, swinging between VSS and VCC, with typical source/sink current capability of 300 mA/600 mA. |
| 6 | VS | power_in | High side floating supply return, recommended range -9 V to 700 V, with absolute limits of VB - 25 V to VB + 0.3 V. |
| 7 | HO | output | High side gate drive output, referenced to VS and swinging between VS and VB, with absolute limits of VS - 0.3 V to VB + 0.3 V. |
| 8 | VB | power_in | High side floating supply, recommended at VS + 10 V to VS + 20 V, with absolute maximum of -0.3 V to 725 V. |
