TPS259461LRPWR TI eFuse | 10-VQFN-HR (2x2) | 4.5V-5.5V, 5A, 28mΩ

Product Overview

The TPS259461LRPWR is a high-performance eFuse power management IC from Texas Instruments, designed to provide robust protection and precise power distribution in space-constrained applications. Housed in a compact 10-pin VQFN-HR package (2mm x 2mm), this device integrates a low on-resistance (28mΩ typical) N-channel MOSFET to support continuous currents up to 5A. Operating over an input voltage range of 4.5V to 5.5V, it offers programmable overcurrent protection, output voltage slew rate control, and thermal shutdown. The TPS259461LRPWR is ideal for hot-swap, USB Type-C, and point-of-load applications where reliable circuit protection is critical.
