LT6108IMS8-1#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; this pin must be tied to the load end of the sense resistor. |
| 2 | EN/RST | input | Enable and latch reset input (LT6108-1): pulled high enables the device, pulled low for longer than typically 40µs enters shutdown, and a low pulse of 2µs to 15µs resets the comparator. |
| 3 | OUTC | output | Open-drain comparator output; the 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; it sources a current equal to the sense voltage divided by the external gain setting resistor RIN. |
| 7 | V+ | power_in | Positive supply pin; it can be connected to either side of the sense resistor, and supply current is drawn through this pin. |
| 8 | SENSEHI | input | Sense amplifier input driven to the same potential as SENSELO; a resistor (typically RIN) from supply to SENSEHI sets IOUT = VSENSE/RIN. |
