TPS3700DDCR2 from Texas Instruments, in a SOT-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	OUTA	output	INA+ comparator open-drain output that is driven low when the INA+ voltage is below (VITP - VHYS) and goes high when the sense voltage returns above VITP; rated 0 to 18 V.
2	GND	power_in	Ground.
3	INA+	input	Connects to the voltage to be monitored through an external resistor divider, and drives OUTA low when the voltage drops below (VITP - VHYS); input range 0 to 6.5 V recommended.
4	INB-	input	Connects to the voltage to be monitored through an external resistor divider, and drives OUTB low when the voltage exceeds VITP; input range 0 to 6.5 V recommended.
5	VDD	power_in	Supply voltage input, connect a 1.8-V to 18-V supply and place a 0.1-µF ceramic capacitor close to this pin.
6	OUTB	output	INB- comparator open-drain output that is driven low when the INB- voltage exceeds VITP and goes high when the sense voltage returns below (VITP - VHYS); rated 0 to 18 V.
