ZXCT1032

V_IN+ max^(a) .................................................................................................. 28 V
Voltage on any pin relative to GND ..................................... -0.6V and V_IN +0.5 V
Maximum differential voltage between V_IN+ and V_IN- (V_SENSE) ................ 500 mV
Junction temperature range ............................................................. -40 to 150
Storage temperature range ............................................................. -55 to 150

Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may reduce device reliability.
NOTES:
(a) Up to a maximum of 24 hours

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
