IR2103STRPBF 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 20 V, with absolute maximum of -0.3 to 25 V referenced to COM. |
| 2 | HIN | input | Logic input for the high side gate driver output (HO), in phase; recommended input range is 0 to VCC. |
| 3 | LIN | input | Logic input for the low side gate driver output (LO), out of phase; recommended input range is 0 to VCC. |
| 4 | COM | power_in | Low side return, the reference for all voltage parameters on this device. |
| 5 | LO | output | Low side gate drive output, swinging between 0 V and VCC. |
| 6 | VS | power_in | High side floating supply return; recommended offset up to 600 V, with logic operational for VS of -5 to +600 V. |
| 7 | HO | output | High side gate drive output, swinging between VS and VB. |
| 8 | VB | power_in | High side floating supply, recommended VS + 10 V to VS + 20 V, with absolute maximum of -0.3 to 625 V referenced to COM. |
