# IR2104STRPBF

**Infineon Technologies** · Gate Drivers · SOIC-8

IR2104STRPBF 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 | Low side and logic fixed supply, recommended to operate from 10 V to 20 V with an absolute maximum of -0.3 V to 25 V referenced to COM. |
| 2 | IN | input | Logic input for the high and low side gate driver outputs (HO and LO), in phase with HO, compatible with 3.3 V, 5 V and 15 V logic, with a range of -0.3 V to VCC + 0.3 V. |
| 3 | SD | input | Logic input for shutdown, where a logic high turns off both HO and LO, with a range of -0.3 V to VCC + 0.3 V. |
| 4 | COM | power_in | Low side return and reference for all voltage parameters, including VCC, VLO, VIN and the logic inputs. |
| 5 | LO | output | Low side gate drive output, swinging between 0 V and VCC. |
| 6 | VS | power_in | High side floating supply return, with an offset of VB - 25 V to VB + 0.3 V and logic operational for VS from -5 V to +600 V. |
| 7 | HO | output | High side gate drive output, referenced to VS and swinging between VS and VB, in phase with IN. |
| 8 | VB | power_in | High side floating supply, recommended at VS + 10 V to VS + 20 V with an absolute maximum of -0.3 V to 625 V referenced to COM. |
