The LT6119-1 has the comparators connected in opposing polarity and the LT6119-2 has the comparators connected in the same polarity. The comparator latch functionality can be enabled or disabled and the comparators can be configured to reset upon power-on. The input and the open-drain outputs of the comparators are independent from the current sense amplifier. The comparator trip points and amplifier gain are configured with external resistors.
The LT6119 is a complete high side current sense device that incorporates a precision current sense amplifier, an integrated voltage reference, and two latching comparators. It features fast step response times of 500ns and low offset voltage up to 200uV maximum.
Two versions are available: the LT6119-1 has comparators connected in opposing polarity, while the LT6119-2 has them connected in the same polarity. Both devices support power-on reset capability and are specified for operation from -40°C to 125°C.
