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. |
