TPS259540DSGT TI eFuse | 8-WSON (2x2) | 5.5A, 2.7V-18V

Product Overview

The TPS259540DSGT is a high-performance eFuse power management IC from Texas Instruments, designed for robust circuit protection in compact applications. Housed in an 8-WSON (2x2 mm) package, it integrates a low on-resistance (RON) MOSFET to minimize power loss and heat dissipation. This device offers adjustable current limiting up to 5.5A, overvoltage protection, and reverse current blocking, making it ideal for hot-swap and power distribution in space-constrained designs.
