LT6108AHMS8-1#PBF from Analog Devices, in a MSOP-8. 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	SENSELO	input	Sense amplifier input that must be tied to the load end of the sense resistor.
2	EN/RST	input	Enable and latch reset input for the LT6108-1: pulled low for longer than typically 40µs it enters shutdown, and pulsing it low for between 2µs and 15µs resets the comparator.
3	OUTC	output	Open-drain comparator output whose off-state voltage may be as high as 60V above V-, regardless of V+ used.
4	V-	power_in	Negative supply pin that is normally connected to ground.
5	INC	input	Inverting input of the comparator, with the other comparator input internally connected to the 400mV reference.
6	OUTA	output	Current output of the sense amplifier that sources a current equal to the sense voltage divided by the external gain setting resistor RIN.
7	V+	power_in	Positive supply pin through which supply current is drawn; when V+ is tied to the load end of the sense resistor, SENSEHI can go up to 0.2V above V+.
8	SENSEHI	input	Sense amplifier input that the internal amplifier drives to the same potential as SENSELO, with a resistor (typically RIN) from supply setting IOUT = VSENSE/RIN.
