MH253KUA

MST Magnesensor Tech MST · Hall Switches · TO-92S

MH253KUA 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 voltage input with an operating range of 2.5 V to 6 V and an absolute maximum of 7 V; reverse VDD protection is not included, so a 100 Ω series resistor in VDD is recommended.
2 GND power_in Ground reference for the device; the reverse-voltage rating on VDD and VOUT is -0.3 V.
3 Output output Open-drain omni-polar switch output with a maximum output current of 25 mA, a low-level output voltage of 400 mV maximum at 10 mA, and an absolute maximum output voltage of 6 V.
