3 Description
The TPS25200-Q1 device is a 5-V eFuse with a
precision current-limit and overvoltage clamp. The
device provides robust protection for load and source
during overvoltage and overcurrent events.
The TPS25200-Q1 device is an intelligent protected
load-switch with a VIN value tolerant to 20 V. In the
event that an incorrect voltage is applied at the IN
pin, the output clamps to 5.4 V to protect the load. If
the voltage at the IN pin exceeds 7.6 V, the device
disconnects the load to prevent damage to the
device, load, or both.
The TPS25200-Q1 device has an internal 67-mΩ
power switch and is intended for protecting the
source, device, and load under a variety of abnormal
conditions. The device provides up to 2.4 A of
continuous load current. The current-limit is
programmable from 85 mA to 2.7 A with a single
resistor to ground. During overload events, the output
current is limited to the level set by the RILIM resistor.
If a persistent overload occurs, the device eventually
enters thermal shutoff to prevent damage to the
TPS25200-Q1 device.
