ShangHai Consonance Elec · Supervisor and Reset ICs · SOT-23

CN61CN33 from ShangHai Consonance Elec, in a SOT-23. 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 RES output Voltage-detect output (open-drain, N-variant). Drives low when VCC is below the detection threshold VDET (3.3V typical for CN61CN33). Releases high-Z (pulled high externally) when VCC exceeds VDET + VHYST. Sink capability: VOL <= 0.3V at ISINK=3.2mA with VCC=3V. Absolute max 20mA; rated to -0.3V to +6.0V.
2 GND power_in Ground / negative supply return.
3 VCC power_in Positive supply and monitored input. Powers the internal comparator, bandgap reference, and output driver, and is also the voltage sensed against VDET. Operating range 1.15V to 5.5V; absolute max -0.3V to +6.0V, 20mA. A 0.1uF bypass capacitor near this pin improves rejection of short supply glitches.
