Overview
The TPS25200DRVT, produced by Texas Instruments, is a 5-V electronic fuse (eFuse) designed to provide robust protection for loads and sources against various abnormal conditions such as overvoltage and overcurrent events. This intelligent protected load switch features an internal 60-mΩ high-side MOSFET and can handle up to 2.5 A of continuous load current. The device is tolerant to input voltages up to 20 V and includes a precision overvoltage clamp and adjustable current limit, making it suitable for a wide range of applications.
