Overview
The TPS25200DRVR is a 5-V electronic fuse (eFuse) developed by Texas Instruments. This device is designed to provide robust protection for loads and sources against overvoltage and overcurrent events. It operates within a voltage range of 2.5 V to 6.5 V and can withstand input voltages up to 20 V. The TPS25200DRVR features an integrated 60-mΩ high-side MOSFET and supports continuous load currents up to 2.5 A. It is particularly useful in applications requiring precision current limiting and overvoltage clamping.
