Infineon Technologies · Gate Drive ICs · SOIC-8

AUIR3241STR 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 IN input Input pin; active high and 3.3V compatible, with VIH of 2.5 to 5.5V and VIL of 0 to 0.8V.
2 GND power_in Ground pin; Vin-gnd maximum is -0.3V to Vout+0.3V and Vcc-gnd maximum is -0.3V to 65V.
3 RS input Current sense input pin; the 1V comparator limits inductor current via the Rs threshold Vrs th of 0.8 to 1.3V.
4 SW output Output of K1; maximum continuous current in the Sw pin is 200 mA.
5 Source passive Connection of the source pin of the Mosfets.
6 Gate output Output of the gate driver; Vgate is at least 11.5V (Vout_th-related gate drive), and the minimum gate resistor Rg is 100 Ohm.
7 Vcc power_in Power supply; operating voltage range is 3 to 36V, with nominal operation specified from 6 to 16V.
8 Out power_out Output of the boost converter; Vout-Vcc maximum voltage is 65V per the absolute maximum ratings.
