IR2109STRPBF

Infineon Technologies · Gate Drivers · SOIC-8

IR2109STRPBF 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 10 to 20 V, with absolute limits of -0.3 V to 25 V referenced to COM.
2 IN input Logic input for the high and low side gate driver outputs (HO and LO), in phase with HO and referenced to COM; VIH minimum 2.9 V and VIL maximum 0.8 V at VCC 10 to 20 V.
3 SD input Logic shutdown input referenced to COM that turns off both channels; positive-going threshold minimum 2.9 V and negative-going threshold maximum 0.8 V at VCC 10 to 20 V.
4 COM power_in Low side return and reference for all voltage ratings and for the IN and SD logic thresholds.
5 LO output Low side gate drive output, limited to VCC + 0.3 V maximum with -0.3 V minimum, with pulsed short-circuit output currents of 120 mA source and 250 mA sink (PW ≤ 10 µs).
6 VS power_in High side floating supply return, with offset tolerated from VB - 25 V to VB + 0.3 V (absolute), rated up to 600 V and dV/dt limited to 50 V/ns.
7 HO output High side gate drive output referenced to VS, limited to VS - 0.3 V minimum and VB + 0.3 V maximum.
8 VB power_in High side floating supply, absolute range -0.3 V to 625 V referenced to COM, recommended VS + 10 V to VS + 20 V.
