TPS3702CX33QDDCRQ1 from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	UV	output	Active-low open-drain undervoltage output that goes low when SENSE falls below the internal undervoltage threshold VIT-, and needs a pull-up resistor of 2.2 kΩ to 10,000 kΩ with an output current of 0.3 mA to 10 mA.
2	GND	power_in	Ground reference pin for the device.
3	SENSE	input	Input for the monitored supply rail, with a recommended input voltage of 0 V to 6.5 V, that drives UV low below the undervoltage threshold and OV low above the overvoltage threshold.
4	SET	input	Threshold configuration input with a recommended pin voltage of 0 V to 6.5 V, used to select the desired threshold voltage configuration per Table 8-1.
5	VDD	power_in	Supply voltage input that must be within 2 V to 18 V, with a 0.1 µF ceramic capacitor recommended close to this pin.
6	OV	output	Active-low open-drain overvoltage output that goes low when SENSE rises above the internal overvoltage threshold VIT+, and needs a pull-up resistor to the desired pull-up voltage.
