TPS3780CDBVR 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	VDD	power_in	Supply voltage input; connect a 1.5 V to 6.5 V supply, with a 0.1 µF ceramic capacitor close to this pin (required for VDD < 1.5 V).
2	OUT1	output	SENSE1 monitor output, an open-drain output on the TPS3780 that is driven low when SENSE1 falls below VIT-, can be pulled up to 6.5 V independent of VDD, and requires a pull-up resistor (RPU 1.5 kΩ to 10 MΩ).
3	OUT2	output	SENSE2 monitor output, an open-drain output on the TPS3780 that is driven low when SENSE2 falls below VIT-, can be pulled up to 6.5 V independent of VDD, and requires a pull-up resistor (RPU 1.5 kΩ to 10 MΩ).
4	SENSE2	input	Sense input for the voltage monitored through an external resistor divider; OUT2 is asserted when the voltage falls below the threshold VIT-, with a recommended operating range of 0 V to 6.5 V.
5	GND	power_in	Ground reference pin.
6	SENSE1	input	Sense input for the voltage monitored through an external resistor divider; OUT1 is asserted when the voltage falls below the threshold VIT-, with a recommended operating range of 0 V to 6.5 V.
