# IR2101STRPBF

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

IR2101STRPBF 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 10 to 20V (absolute maximum 25V). |
| 2 | HIN | input | Logic input for high side gate driver output (HO), in phase with HO (IR2101); 3.3V, 5V and 15V logic compatible. |
| 3 | LIN | input | Logic input for low side gate driver output (LO), in phase with LO (IR2101); 3.3V, 5V and 15V logic compatible. |
| 4 | COM | power_in | Low side return; ground reference for logic inputs and the VO and IO parameters. |
| 5 | LO | output | Low side gate drive output, swings 0 to VCC. |
| 6 | VS | power_in | High side floating supply return (offset), operational up to 600V. |
| 7 | HO | output | High side gate drive output, swings from VS to VB. |
| 8 | VB | power_in | High side floating supply, VS+10V to VS+20V recommended (absolute maximum 625V). |
