HAL248DSO
Hallwee · Hall Switches · SOT-23-3L
HAL248DSO 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; the electrical characteristics give an operating voltage of 1.8 V to 5.5 V, and the absolute maximum supply voltage is 7 V. |
| 2 | Gnd | power_in | Ground pin (接地引脚). |
| 3 | Out | output | Open-drain output: the transistor is driven low when the magnetic flux exceeds the BOP operate point and goes high (BRP) in the absence of a field, holding its last state during sleep periods. |
