Overcurrent Battery Fault Protection

The LT6108 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.
