IR4426STR from UMW, 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 | NC | unconnected | No connection; this pin is not connected internally. |
| 2 | INA | input | Input to Channel A, with VIN rated from -12 V to 25 V, VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 3 | GND | power_in | Ground pin to which all signals are referenced; the device tolerates noise spikes of up to 5 V of either polarity on this pin without damage. |
| 4 | INB | input | Input to Channel B, with VIN rated from -12 V to 25 V, VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 5 | OUTB | output | Output of Channel B, with 2 A peak source current and the ability to withstand reverse currents up to 0.5 A without latch-up. |
| 6 | VCC | power_in | Bias supply input with a 4.5 V to 20 V operating range and a 25 V absolute maximum rating. |
| 7 | OUTA | output | Output of Channel A, with 2 A peak source current and the ability to withstand reverse currents up to 0.5 A without latch-up. |
| 8 | NC | unconnected | No connection; this pin is not connected internally. |
