LM25056A Datasheet System Power Measurement-ic

Manufacturer: Texas Instruments

Overview: LM25056A www.ti.com SNVS785A – JANUARY 2011 – REVISED APRIL 2013 LM25056A System Power Measurement IC with PMBus Check for Samples:.

General Description

The LM25056A combines high performance analog and digital technology with a PMBus™ compliant SMBus™/I2C interface to accurately measure the operating conditions of electrical systems including computing and storage blades connected to a backplane power bus.

The LM25056A continuously supplies real-time power, voltage, current, and temperature data to the system management host via the SMBus interface.

The LM25056A monitoring block captures both realtime and average values of subsystem operating parameters (VIN, IIN, PIN, VAUX) as well as peak power.
