CH912LSR

COSEMITECH · Hall Sensor · SOT-23-3L

CH912LSR from COSEMITECH, in a SOT-23-3L. 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. Operating range 1.65V to 5.5V; absolute max 6V. Recommend 0.1uF decoupling capacitor to GND at the pin.
2 OUT output Push-pull digital output. Pulled low when
3 GND power_in Ground reference pin.

CAD (KiCad official)

  • Symbol: CH912LSR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: ch912lsr-etched.step / ch912lsr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ch912lsr.step / ch912lsr.glb are the bare package body.

Provenance

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

  • Datasheet: COSEMITECH datasheet (9 pp, sha256 d1118d62b1014ac0, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
