AH422SU
Alfa(中科阿尔法) · Hall Switches · SOT-23-3L
AH422SU 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 |
|---|---|---|---|
