AUIRS2118STR

Infineon Technologies · Gate Drive ICs · SOIC-8

AUIRS2118STR 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 Low-side and logic fixed supply, recommended operating range 10 V to 20 V (absolute maximum 25 V), with undervoltage lockout.
2 IN input Logic input for gate driver output HO, out of phase with HO (AUIRS2118), CMOS Schmitt-triggered with pull-up, range 0 V to VCC.
3 COM power_in Logic ground, the reference for all absolute maximum voltage ratings.
4 NC unconnected No connection.
5 NC unconnected No connection.
6 VS power_in High-side floating supply return, offset operational up to 600 V and tolerant to negative transients.
7 HO output High-side gate drive output, swinging between VS and VB with typical 290 mA source and 600 mA sink pulsed current.
8 VB power_in High-side floating supply, operating at VS+10 V to VS+20 V (absolute maximum 625 V).

CAD (KiCad official)

  • Symbol: AUIRS2118STR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: auirs2118str-etched.step / auirs2118str-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); auirs2118str.step / auirs2118str.glb are the bare package body.
