JXW1603D

OVERVOLTAGE AND OVERCURRENT PROTECTION IC

Description

Features

The JXW1603 provides robust protection for load and

source during overvoltage and overcurrent events. The

device continuously monitors the input voltage, the input

current, and environmental temperature. In the event that

an incorrect voltage is applied at input, the output will

clamp to 5.5V to protect the load. If the input voltage ex-

ceeds over-voltage threshold, the device disconnects the

load to prevent damage to the device and/or load. In the

case of an overcurrent condition, it limits the system cur-

rent at the threshold value, and if the overcurrent persists,

switches off the pass FET after blanking time. Both input

over-voltage and input overcurrent threshold are user-

programmable. The device also monitors environmental

temperature with Negative Temperature Coefficient

(NTC) thermistor as well as die temperature, and switch-

es off when either of them exceeds pre-determined

threshold. When the device is controlled by a processor,

the status information about fault conditions can be pro-

vided to the host.
