# CN61CN33

**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. |

## CAD (KiCad official)

- Symbol: `CN61CN33`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `cn61cn33-etched.step` / `cn61cn33-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cn61cn33.step` / `cn61cn33.glb` are the bare package body.
