IRS2118STRPBF

Infineon Technologies · Gate Drive ICs · SOIC-8

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.
