Current Sense Latch
Overview
Analog latch devices with digital reset. Specifically designed to provide pulse-by-pulse current limiting for switch-mode power supply systems, but many other application are also feasible. Its function is to provide a latching switch action upon sensing an input threshold voltage, with reset accomplished by an external clock signal. Can be interfaced directly with many kinds of pulse width modulating control IC's, including the SG1524, SG1525A and SG1527A.
