TPS259631DDAT TI eFuse | 8-SO-POWERPAD | 5.5V, 5A, Adjustable Current Limit

Product Overview

The TPS259631DDAT is a high-performance eFuse power management IC from Texas Instruments, designed to provide robust protection for power distribution systems. Housed in a compact 8-SO-POWERPAD package, this device integrates a low on-resistance N-channel MOSFET with a comprehensive set of protection features, including overcurrent, overvoltage, undervoltage, and thermal shutdown. It supports an input voltage range from 2.7V to 5.5V and can deliver up to 5A continuous current. The adjustable current limit allows designers to set precise thresholds via an external resistor, making it ideal for a wide range of applications requiring reliable power path protection.
