IRS2127STRPBF

Infineon Technologies · Gate Drive ICs · SOP-8

IRS2127STRPBF from Infineon Technologies, in a SOP-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, recommended operating range 10 V to 20 V referenced to COM.
2 IN input Logic input for gate driver output HO, in phase with HO for the IRS2127S/IRS21271S, with VIN limited to 0 V to VCC.
3 FAULT output Open-drain, negative-logic indicator that goes low when an over-current shutdown has occurred, with VFLT limited to 0 V to VCC.
4 COM power_in Logic ground, the reference for all absolute voltage ratings.
5 VS power_in High-side floating supply return, rated for offset up to 600 V with logic operational from -5 V to +600 V.
6 CS input Current sense input to the current sense comparator, with CS voltage limited to VS to VS + 5 V and a 250 mV positive-going threshold for this variant.
7 HO output High-side gate drive output referenced to VS, with VHO limited to VS to VB and peak source/sink current of 200 mA / 420 mA.
8 VB power_in High-side floating supply, rated VS + 12 V to VS + 20 V for the IRS2127 variant.
