IRS21271STRPBF

Infineon Technologies · Gate Drive ICs · SOIC-8

IRS21271STRPBF 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, with a recommended operating range of 10 V to 20 V and an absolute maximum of 25 V.
2 IN input Logic input for gate driver output HO, in phase with HO for the IRS21271, with VIN limited to 0 V to VCC.
3 FAULT output Open-drain, negative-logic output that indicates an over-current shutdown has occurred.
4 COM power_in Logic ground, to which all voltage parameters are referenced.
5 VS power_in High-side floating supply return, rated for a high-side floating offset voltage up to 600 V.
6 CS input Current sense input to the current sense comparator, with a positive-going threshold of 1.8 V typical for the IRS21271.
7 HO output High-side gate drive output, swinging between VS and VB.
8 VB power_in High-side floating supply, rated at VS + 9 V to VS + 20 V for the IRS21271.
