... The LT6100 has a separate supply input, which operates from 2.7V to 36V and draws only 60µA. When V powered down, the sense pins are biased off. This pre- vents loading of the monitored circuit, irrespective of the sense voltage. The LT6100 is available in an 8-lead DFN and MSOP package ...

... Noise Filtering The LT6100 provides signal filtering via pin FIL that is internally connected to the resistors R may be used to filter the input signal entering the LT6100’s internal op amp, and should be used when fast ripple current or transients flow through the sense resistor.

... U APPLICATIO S I FOR ATIO Power Down While Connected to a Battery Another unique benefit of the LT6100 is that you can leave it connected to a battery even when it is denied power. When the LT6100 loses power or is intentionally powered down, its inputs remain high impedance (see Figure 8). ...
