IR4426STR

UMW · Gate Drivers · SOP-8

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.
