IR2181PBF 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 | HIN | input | Logic input for the high side gate driver output HO, in phase, compatible with 3.3V and 5V logic and clamped internally by a 5.2V zener diode. |
| 2 | LIN | input | Logic input for the low side gate driver output LO, in phase, compatible with 3.3V and 5V logic and clamped internally by a 5.2V zener diode. |
| 3 | COM | power_in | Low side return and reference ground for all voltages on the device, with recommended VCC supply range of 10 to 20 V. |
| 4 | LO | output | Low side gate drive output, with VLO between 0 V and VCC. |
| 5 | VCC | power_in | Low side and logic fixed supply, with recommended range of 10 to 20 V and absolute maximum of -0.3 to 25 V. |
| 6 | VS | power_in | High side floating supply return, with offset up to 600 V and transient dV/dt limited to 50 V/ns. |
| 7 | HO | output | High side gate drive output, with VHO between VS and VB. |
| 8 | VB | power_in | High side floating supply, with recommended range of VS + 10 V to VS + 20 V and absolute maximum of -0.3 to 625 V. |
