CN61C

ShangHai Consonance Elec · Voltage References · SOT-23-3

CN61C 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 RES output Voltage detection output that goes low when VCC is below the detection threshold and goes high when VCC rises above the threshold plus hysteresis (VRES + VHYST); open-drain on the CN61CN25/CN61CN33 variants, absolute maximum -0.3V to +6.0V and 20mA.
2 GND power_in Negative power supply input (ground).
3 VCC power_in Positive power supply input that both powers the internal circuitry and is the monitored voltage, operating range 1.15V to 5.5V and absolute maximum -0.3V to +6.0V.
