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. The overall propagation delay of the LT6108 is typically only 1.4µs, allowing for quick reaction to overcurrent conditions. ...
