DFN Packages The LT®6108 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 LT6108-1 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 easy interface to other system components. n APPLICATIONS n n n n n Overcurrent and Fault Detection
