MH253EUA
MST Magnesensor Tech MST · Hall Switches · TO-92S
MH253EUA from MST Magnesensor Tech MST, in a TO-92S. 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 pin; the datasheet gives an operating supply voltage range of 2.5 V to 6 V (absolute maximum 7 V), and reverse VDD is not protected. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | Out | output | Open-drain output that sinks up to 25 mA absolute maximum (output low voltage 400 mV at 10 mA), with output leakage of 10 µA maximum when Vout is high at B < BRP. |
