LM25056A Description
The LM25056A bines high performance analog and digital technology with a PMBus™ pliant SMBus™/I2C interface to accurately measure the operating conditions of electrical systems including puting 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...
