LT6105
Precision, Extended Input
Range Current Sense Amplifier
FEATURES DESCRIPTION n The LT®6105 is a micropower, precision current sense
amplifier with a very wide input common mode range.
The LT6105 monitors unidirectional current via the voltage across an external sense resistor. The input common
mode range extends from –0.3V to 44V, with respect to
the negative supply voltage (V –). This allows the LT6105
to operate as a high side current sense monitor or a low
side current sense monitor. It also allows the LT6105 to
monitor current on a negative supply voltage, as well as
continuously monitor a battery from full charge to depletion.
The inputs of LT6105 can withstand differential voltages
up to ±44V, which makes it ideal for monitoring a fuse or
MOSFET switch. Very Wide, Over-the-Top®, Input Common Mode Range
