CN809M

ShangHai Consonance Elec · Supervisor and Reset ICs · SOT-23-3

CN809M from ShangHai Consonance Elec, 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 GND power_in Ground reference for the device.
2 RESET output Active-low CMOS reset output. Driven low when VCC falls below the 4.38 V reset threshold; remains low for at least 140 ms after VCC rises above VRES + VHYST, then transitions high. Drives 0.3 V max at ISINK up to 5 mA (VCC=4 V) and VCC-0.4 V min at ISRC up to 2.5 mA (VCC=5 V).
3 VCC power_in Positive supply input; also the voltage being monitored for the reset threshold comparison. Operating range 1.15 V (min output valid) to 5.5 V (absolute max 6.0 V). Typical IVCC = 3.2 µA at VCC = 3 V.

  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: cn809m-etched.step / cn809m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn809m.step / cn809m.glb are the bare package body.

Provenance

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

  • Datasheet: ShangHai Consonance Elec datasheet (7 pp, sha256 bbeb80fd1a0c3663, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
