HX61CN5002MR from HANSCHIP semiconductor, 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	Chip output pin. N-channel open-drain detector output; requires an external pull-up resistor (application circuit shows 100kΩ). Output pulls low when VIN falls below VDET (5.0V typical), releases high above VS = 1.05 × VDET.
2	VSS	power_in	Chip ground reference pin.
3	VIN	power_in	Supply/sense input pin. Operating voltage 1.5V-12V (absolute max 15V); this is both the supply and the monitored voltage node.
