LM5056APMHX/NOPB TI Power Management IC | 28-HTSSOP | 80V, 5A

Product Overview

The LM5056APMHX/NOPB from Texas Instruments is a high-voltage, high-current power management IC designed for hot-swap and power-over-Ethernet (PoE) applications. It integrates a 80V, 5A N-channel MOSFET with current sensing and fault protection, enabling safe insertion and removal of circuit cards in live backplanes. The device operates from 2.7V to 80V and features programmable current limit, under-voltage lockout (UVLO), and over-temperature protection. Its 28-HTSSOP package offers excellent thermal performance for demanding industrial and telecom environments.
