LT6108HMS8-2#PBF Description

The LT6108HMS8-2#PBF is a complete high-side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference, and a comparator. Two versions of the LT6108 are available. The LT6108HMS8-2#PBF has a latching comparator and the LT6108-2 has a non-latching comparator. In addition, the current sense amplifier and comparator inputs and outputs are directly accessible. The amplifier gain and comparator trip point are configured by external resistors. The open-drain comparator output allows for an easy interface to other system components.
