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.
