LM25066 Overview
The LM25066 bines a high-performance hotswap controller with a PMBus™ pliant SMBus/I2C interface to accurately measure, protect and control the electrical operating conditions of puting and storage blades connected to a backplane power bus. The LM25066 continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface. The LM25066 control block...
