3 Description
The TPS25200 is a 5V eFuse with precision
current limit and overvoltage clamp. The device
provides robust protection for load and source during
overvoltage and overcurrent events.
The TPS25200 is an intelligent protected load switch
with VIN tolerant to 20V. In the event that an incorrect
voltage is applied at IN, the output clamps to 5.4V to
protect the load. If the voltage at IN exceeds 7.6V, the
device disconnects the load to prevent damage to the
device and/or load.
The TPS25200 has an internal 60mΩ power switch
and is intended for protecting source, device, and
load under a variety of abnormal conditions. The
device provides up to 2.6A of continuous load current.
Current limit is programmable from 85mA to 2.9A with
a single resistor to ground. During overload events
output current is limited to the level set by RILIM. If
a persistent overload occurs the device eventually
goes into thermal shutoff to prevent damage to the
TPS25200.
