Overview
ZXCT1032 High-side inrush controller and electronic fuse Description The ZXCT1032 is a high-side current monitor that drives a PMOS or PNP transistor to provide in-rush current limit and over-current protection.
The ZXCT1032 includes a high accuracy high-side current monitor, a start-up timer and a re-try inhibit timer.
The ZXCT1032 takes the voltage developed across a current shunt resistor and compares this with an externally set trip point.
It works in three modes: • • • Linear soft-start Over-current detector Over-current disconnect/fuse While in this mode the internal current monitor continually checks the output current and compares it to the trip-current level determined by VISET.
