IRS2118STRPBF 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 | Logic and gate drive supply, rated 10 V to 20 V in the recommended operating conditions. |
| 2 | IN | input | Logic input for gate driver output HO; on the IRS2118 it is out of phase with HO, and the input is a CMOS Schmitt-triggered input with pull-down. |
| 3 | COM | power_in | Logic ground; all voltage parameters are referenced to COM. |
| 4 | NC | unconnected | No connect on the IRS2118 (listed as NC for IRS2117/IRS2118 in the lead definitions). |
| 5 | NC | unconnected | No connect. |
| 6 | VS | power_in | High-side floating supply return; VS offset is rated to 600 V, with a transient of -50 V negative for 50 ns. |
| 7 | HO | output | High-side gate drive output, driving the high-side N-channel power MOSFET or IGBT. |
| 8 | VB | power_in | High-side floating supply; VB must be held 10 V to 20 V above VS in the recommended operating conditions. |
