Corebai Microelectronics · Supervisor And Reset ICs · SOT-23-3
CBM809LST3 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 pin; all signals are referenced to ground (0 V). |
| 2 | RESET | output | Active-low push-pull reset output (CBM809X): it is held low while VCC is below the reset threshold and stays low for 240 ms typical after VCC rises above the threshold. |
| 3 | VCC | power_in | Monitored supply voltage input; the reset threshold is 4.63 V for CBM809L, and the supply operates from 1.0 V to 5.5 V. |
