TPS3702CX33DDCR from Texas Instruments, in a TSOT-23-6. 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	UV	output	Active-low, open-drain undervoltage output. Goes low when the SENSE voltage falls below the internally set undervoltage threshold (VIT-). Requires an external pull-up resistor (2.2 kΩ to 10 kΩ recommended) terminated to the desired pull-up voltage (up to 18 V).
2	GND	power_in	Device ground reference.
3	SENSE	input	Input for the monitored supply voltage rail (0 V to 6.5 V range). When SENSE drops below the undervoltage threshold, the UV pin is driven low. When SENSE rises above the overvoltage threshold, the OV pin is driven low.
4	SET	input	Threshold configuration select input (0 V to 6.5 V). Tie high or low to choose between the two factory-programmed threshold configurations of the device. VIL(set) ≤ 250 mV; VIH(set) ≥ 750 mV.
5	VDD	power_in	Supply voltage input pin, 2 V to 18 V. Place a 0.1 µF ceramic decoupling capacitor close to this pin. Typical quiescent supply current is 7 µA.
6	OV	output	Active-low, open-drain overvoltage output. Goes low when the SENSE voltage rises above the internally set overvoltage threshold (VIT+). Requires an external pull-up resistor (2.2 kΩ to 10 kΩ recommended) terminated to the desired pull-up voltage (up to 18 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps3702cx33ddcr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps3702cx33ddcr-etched.step`	3.0 MB	You want the part with `TPS3702CX33DDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 712 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
