ISP452HUMA1

Infineon Technologies · Power Distribution Switches · SOT-223-4

ISP452HUMA1 from Infineon Technologies, in a SOT-223-4. 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 OUT output Protected high-side power output; leakage current is 2 µA typ and 5 µA max at Vin low and Tj = -40...+25 °C (7 µA at Tj = 150 °C), and the current limit is 0.7 to 2.4 A.
2 GND power_in Logic ground; operating current IGND is 1 mA typ and 1.6 mA max at Vin = 5 V.
3 IN input Input that activates the power switch on a logical high signal; allowable input voltage range is -3.0 V to Vbb, with input current limited to ±5 mA.
4 Vbb power_in Positive power supply voltage; operating voltage range is 5.0 V to 34 V, with a 40 V maximum supply voltage rating.
