LT6108HMS8-2#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	input	Enable input for the LT6108-2 (not EN/RST, which applies to the LT6108-1): pulling it high enables the device, and pulling it low for longer than typically 40µs puts the device into shutdown.
3	OUTC	output	Open-drain comparator output whose off-state voltage may be as high as 60V above V-, regardless of the V+ used.
4	V-	power_in	Negative supply pin, normally connected to ground.
5	INC	input	Inverting input of the comparator; the other comparator input is 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 (2.7V to 60V per the electrical characteristics) that can connect to either side of RSENSE, with supply current drawn through this pin.
8	SENSEHI	input	Sense amplifier input that the internal amplifier drives to the same potential as SENSELO; a resistor (typically RIN) from supply to SENSEHI sets IOUT = VSENSE/RIN.
