Changjing · Supervisor and Reset ICs · SOT-23-3L
CJ809C263M from Changjing, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Ground reference (0 V). Common return for supply and output. |
| 2 | VOUT | output | Voltage detection output pin, CMOS push-pull, active-low. Asserts low when VDD falls below -VDET (2.63 V); returns high after the internal 210 ms (typ) release delay once VDD recovers above -VDET+VHYS. |
| 3 | VDD | power_in | Positive supply and monitored input. Operating range 0.95 V to 7.0 V; absolute max VSS-0.3 V to VSS+8 V. |
