CBM810JST3

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

CBM810JST3 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; all signals are referenced to ground (0 V).
2 RESET output Push-pull active-high reset output that asserts while VCC is below the reset threshold and stays asserted for 240 ms typical after VCC rises above the threshold.
3 VCC power_in Monitored supply voltage input; the reset threshold is set by the part suffix, which is 4.00 V typical for CBM810J.
