HX61CN3602MR 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 pin. N-channel open-drain output (requires external pull-up resistor, e.g. 100kΩ). Output pulls low when VIN falls below VDET (3.6V nominal); releases high (via pull-up) when VIN rises above Vs = 1.05 × VDET. IOL ≥ 0.5mA min (typ 1mA) at VOUT=0.2V, VIN=2V.
3	VIN	power_in	Sensed input voltage / supply pin (VDD = VIN per electrical spec). Operating range 1.5V to 12V, absolute max 15V. This is both the monitored voltage and the chip supply.
2	VSS	power_in	Ground / negative supply reference.
