Shanghai Siproin Microelectronics · Supervisor and Reset ICs · SOT-23

SSP61CN3902MR from Shanghai Siproin Microelectronics, 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 VOUT output Detector output. N-channel open-drain; pulls low (to VSS) when VDD <= VDET(-), and is high-impedance when VDD > VDET(+). Requires an external pull-up resistor (e.g. 100 kOhm to VDD, or 47 kOhm when driving a microcomputer RESET pin). Output sink current IOL >= 0.5 mA at VOUT=0.2V, VIN=2V.
2 GND power_in Ground / VSS reference for the device. Also the sink return for the open-drain output driver.
3 VIN power_in Supply voltage input and monitored voltage rail. Operating range 0.7V to 10V; absolute maximum 8.0V (-0.3 to 8.0V). The detector trips when this rail crosses the 3.9V (+/-2%) threshold with built-in hysteresis (2%-10% of VDET).
