DESCRIPTION
The LT96105 is a micropower, precision current sense
amplifier with a very wide input common mode range.
The LT6105 monitors unidirectional current via the volt-
age across an external sense resistor. The input common
mode range extends from -0.3V to 44V, with respect to
the negative supply voltage (V7). This alows 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 batteryfromfullcharge todepletion.
The inputs of LT6105 can withstand differential voltages
up to +44V, which makes it ideal for monitoring a fuse or
MOSFET switch.
Gain is configured with external resistors from 1VN to
100VN. The input common mode rejection and power
supply rejection are in excess of 100dB and the input offset
voltage is less than 300pV. A typical slew rate of 2V/μs
ensures fast response to unexpected current changes.
The LT6105 can operate from an independent power
supply of 2.85V to 36V and draws only 150μA. When
V+ is powered down, the sense pins are biased off. This
prevents loading of the monitored circuit, irrespective of
the sense voltage. The LT6105 is available in a 6-lead DFN
and 8-lead MSOP package.
