LT6109HMS-1#PBF

Analog Devices · Comparators · MSOP-10

LT6109HMS-1#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; high enables, low for longer than typically 40µs enters shutdown, and a low pulse of 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 V+ used.
4 OUTC1 output Open-drain comparator 1 output whose off-state voltage may be as high as 60V above V- regardless of V+ used.
5 V- power_in Negative supply pin, normally connected to ground.
6 INC1 input Inverting input of comparator 1, with the other input internally connected to the 400mV reference.
7 INC2 input Noninverting input of comparator 2 on the LT6109-1, with the other input internally connected to the 400mV reference.
8 OUTA output Current output of the sense amplifier, sourcing 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) that can connect to either side of the sense resistor and carries the supply current.
10 SENSEHI input Sense amplifier input driven to the same potential as SENSELO, where a resistor (typically RIN) from supply sets IOUT = VSENSE/RIN.
