LM25056
Overview
The LM25056 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 LM25056 continuously supplies real-time power, voltage, current, and temperature data to the system management host via the SMBus interface.
