LT6109IMS-2#PBF from Analog Devices, in a MSOP-10. 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: pulling it high enables the LT6109, pulling it low for longer than typically 40µs puts it in shutdown, and pulsing it low for 2µs to 15µs resets the comparators. |
| 3 | OUTC2 | output | Open-drain comparator 2 output whose off-state voltage may be as high as 60V above V-, regardless of the V+ used. |
| 4 | OUTC1 | output | Open-drain comparator 1 output whose off-state voltage may be as high as 60V above V-, regardless of the V+ used. |
| 5 | V- | power_in | Negative supply pin that is normally connected to ground. |
| 6 | INC1 | input | Inverting input of comparator 1; the second input of this comparator is internally connected to the 400mV reference. |
| 7 | INC2 | input | For the LT6109-2 this is the inverting input of comparator 2, and its second input is internally connected to the 400mV reference. |
| 8 | 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. |
| 9 | V+ | power_in | Positive supply pin (2.7V to 60V); it can connect to either side of RSENSE, and when tied to the load end SENSEHI can go up to 0.2V above V+. |
| 10 | SENSEHI | input | Sense amplifier input driven to the same potential as SENSELO; a resistor RIN from supply to SENSEHI sets IOUT = VSENSE/RIN. |
