TPS25921LDR TI eFuse | 8-SOIC | 5.5V, 5A, 28mΩ

Product Overview

The TPS25921LDR 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-SOIC package, this device integrates a low on-resistance (28mΩ) N-channel MOSFET to support continuous currents up to 5A. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for various low-voltage applications. The TPS25921LDR features programmable overcurrent protection, output slew rate control, and thermal shutdown, ensuring safe and reliable operation in demanding environments.
