Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LM25066A SNVS700G – DECEMBER 2010 – REVISED OCTOBER 2016 LM25066A System Power Management and Protection IC With PMBus™.

General Description

The LM25066A combines a high-performance hotswap controller with a PMBus™ compliant SMBus/I2C interface to accurately measure, protect and control the electrical operating conditions of computing and storage blades connected to a backplane power bus.

The LM25066A continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface.

The LM25066A control block includes a unique hotswap architecture that provides current and power limiting to protect sensitive circuitry during insertion of boards into a live system backplane, or any other hot power source

Key Features

  • 1 Input Voltage Range: 2.9 V to 17 V.
