CN810T from ShangHai Consonance Elec, 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 pin for the supervisor circuit, as shown in the pinout diagram of the SOT23-3 package. |
| 2 | RESET | output | CMOS reset output for the CN810T, active high: it is driven high while VCC is below the reset threshold VRES (3.08V typ for CN810T) and stays high for at least 140 ms after VCC rises above VRES + VHYST, then goes low. |
| 3 | VCC | power_in | Positive supply input that powers the internal circuit and is also the voltage being monitored; the datasheet gives an absolute maximum of -0.3V to +6.0V relative to GND and an operating minimum of 1.15V. |
