**Advanced Analog Technology** · Hall Switches · TSOT23-3L

FD2H001BAR-G1 from Advanced Analog Technology, in a TSOT23-3L. 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 | VDD | power_in | Positive supply pin; the datasheet gives an operating supply range of 2.4 V to 5.5 V. |
| 2 | Q | output | Open-drain output that goes low when the applied magnetic flux density exceeds the switching threshold. |
| 3 | VSS | power_in | Ground pin, the device reference (GND). |
