LM5056 Overview
The LM5056/LM5056A bines high-performance analog and digital technology with a PMBus™ pliant SMBus™ and I2C interface to accurately measure the electrical operating conditions of systems connected to a backplane power bus. The LM5056/LM5056A continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface. The LM5056/LM5056A monitoring block...
