AH402HSU
Alfa(中科阿尔法) · Hall Switches · SOT-23-3L
AH402HSU from Alfa(中科阿尔法), in a SOT-23-3L. 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 | Supply input with an operating range of 3.0 V to 60 V, reverse-voltage protection on the supply pin, and an 80 V overvoltage protection capability; the absolute maximum supply voltage is -60 V to 80 V. |
| 2 | VOUT | output | Open-collector digital output that can drive up to 30 mA; the absolute maximum output voltage is 80 V and the absolute maximum output current is 40 mA. |
| 3 | GND | power_in | Ground reference pin of the device. |
