MGH201B1T3

Megain · Hall Switches · SOT-23-3

MGH201B1T3 from Megain, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Supply voltage input, 3.5V to 30V operating range (30V absolute max). Recommend 100nF bypass capacitor between VDD and GND placed close to the device. Quiescent current 5mA (B < BRP).
2 VOUT output Hall-switch output with internal 8kΩ pull-up resistor to VDD (MGH201B variant). Latched output: drives LOW (VDSon ≤ 0.5V @ 20mA) when magnetic flux exceeds BOP, drives HIGH when field crosses BRP. Maximum output current 50mA; max output voltage 30V.
3 GND power_in Ground reference / return.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Megain datasheet (7 pp, sha256 18c66a071cd5049f, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
