IR2108PBF from Infineon Technologies, in a PDIP-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 V to 20 V, with an absolute maximum range of -0.3 V to 25 V referenced to COM. |
| 2 | HIN | input | Logic input for the high side gate driver output HO (in phase), referenced to COM, with VIH minimum 2.9 V and VIL maximum 0.8 V. |
| 3 | LIN | input | Logic input for the low side gate driver output LO (out of phase), referenced to COM, with VIH minimum 2.9 V and VIL maximum 0.8 V. |
| 4 | COM | power_in | Low side return and the reference for all absolute maximum voltage ratings and the HIN/LIN logic inputs. |
| 5 | LO | output | Low side gate driver output, swinging between 0 V and VCC. |
| 6 | VS | power_in | High side floating supply return, operating up to 600 V with logic operation down to -5 V and dVS/dt limited to 50 V/ns. |
| 7 | HO | output | High side gate driver output, swinging between VS and VB. |
| 8 | VB | power_in | High side floating supply, recommended VS + 10 V to VS + 20 V, with an absolute maximum of 625 V referenced to COM. |
