CBM810ZST3

Corebai Microelectronics · Supervisor And Reset ICs · SOT-23-3

CBM810ZST3 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, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for all signals, with all signals referenced to 0 V.
2 RESET output Push-pull active-high reset output that is held high while VCC is below the reset threshold and for 240 ms typical after VCC rises above it.
3 VCC power_in Monitored supply voltage, with a supply range of 1.0 V to 5.5 V and an absolute maximum of -0.3 V to +6 V.

CAD (KiCad official)

  • Symbol: CBM810ZST3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: cbm810zst3-etched.step / cbm810zst3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cbm810zst3.step / cbm810zst3.glb are the bare package body.
