HE61CN2402MR

HEERMICR · Supervisor and Reset ICs · SOT-23-3

HE61CN2402MR from HEERMICR, in a SOT-23-3. 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 VOUT output N-channel open-drain detector output. Pulled low to VSS when VIN <= VDET(-) (~2.4V); high-impedance (Hi-Z) when VIN > VDET(+). Requires an external pull-up resistor (e.g. 47kΩ). Sink capability IOL >= 0.5 mA at VOUT = 0.2V with 2V supply.
2 GND power_in Ground / VSS reference for the detector and open-drain output source.
3 VIN power_in Supply and sense input. Operating range 0.7V to 10V (absolute maximum 8V per Absolute Maximum Ratings). Voltage on this pin is compared against the internal 2.4V reference to drive the detector output.
