HAL1201NSO
Hallwee · Hall Switches · SOT-23-3L
HAL1201NSO from Hallwee, 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 voltage pin, operating range 1.8 V to 5.5 V in the DC table (absolute maximum 6 V), with an external bypass capacitor recommended close to the device. |
| 2 | OUT | output | CMOS output that goes low when a south pole field exceeds Bop (50 G max) and releases below Brp, rated for 0.5 mA with VOL of 0.2 V max (absolute maximum 6 V and 1 mA). |
| 3 | GND | power_in | Ground reference pin for the supply and output. |
