CBM809JST3

Corebai Microelectronics · Monitors & Reset Circuits · SOT-23-3

CBM809JST3 from Corebai Microelectronics, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin; all signals are referenced to ground (0 V).
2 RESET output Active-low push-pull reset output for CBM809X: it is asserted while VCC is below the reset threshold and remains asserted for 240 ms (typical) after VCC rises above the threshold.
3 VCC power_in Monitored supply voltage input; the device is specified for VCC from 1.0 V to 5.5 V.

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: CBM809JST3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3, generated on the KiCad land (body 2.37 x 2.92 mm, terminals on the pads, 1.0050000000000001 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: cbm809jst3-etched.step / cbm809jst3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cbm809jst3.step / cbm809jst3.glb are the bare package body.

Provenance

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

  • Datasheet: Corebai Microelectronics datasheet (13 pp, sha256 78d9ec07286e0192, retrieved 2026-11-12, 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: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
