AH1889-Z-7 from Diodes Incorporated, in a SOT-553-5. 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 | OUTPUT2 | output | North pole detecting output pin (active low), which is pulled low when a North pole of sufficient strength turns it on. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | NC | unconnected | No connection; not connected internally, and may be left open or tied to ground. |
| 4 | VDD | power_in | Power supply voltage pin, operating from 1.65 V to 3.6 V. |
| 5 | OUTPUT1 | output | South pole detecting output pin (active low), which is pulled low when a South pole of sufficient strength turns it on. |
