DFN Packages The LT®6118 is a complete high side current sense device
that incorporates a precision current sense amplifier, an
integrated voltage reference and a latching comparator.
The comparator latch functionality can be enabled or
disabled and the comparator can be configured to reset
upon power-on. The input and the open-drain output of
the comparator are independent from the current sense
amplifier. The comparator trip point and amplifier gain are
configured with external resistors. n Applications n n n n Overcurrent and Fault Detection
