HAL5781SO
Hallwee · Hall Switches · SOT-23-3L
HAL5781SO 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 | VDD | power_in | Supply voltage pin with a stated operating range of 3.5 to 24 V; the output changes state above 2.2 V, but magnetic characteristics are only specified above 3.5 V. |
| 2 | Gnd | power_in | Ground pin for the device. |
| 3 | Out | output | Open-drain output that goes low (output transistor on) when a sufficiently strong N-pole field reaches BOP (typ. 90 GS) and goes high when the field falls to BRP (typ. 120 GS); VOUT and IOUT absolute maximum ratings are given in the limits table. |
