HX61CC3602MR from HX hengjiaxing, in a SOT-23-3L. 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 (CMOS push-pull). Held HIGH (≈VIN) while VIN is above the detect threshold VDET (typ. 3.6 V) and pulled LOW when VIN falls below VDET. Built-in hysteresis Vs = 1.05×VDET releases the output. Absolute rating: VSS-0.3 V to VIN+0.3 V. Typical sink capability IOL ≥ 0.5 mA at VOUT = 0.2 V (VIN = 2 V).
2	VSS	power_in	Ground / negative supply reference for the detector. In SOT-23-3 this is pin 2 (per the datasheet pin table which shows SOT23-3 pin 2 = VSS).
3	VIN	power_in	Sense / supply input (starts and powers the detector, also the monitored voltage; datasheet notes VDD = VIN). Operating range 1.5 V to 12 V; absolute maximum 15 V. In SOT-23-3 this is pin 3.
