LM5064 Description
The LM5064 bines a high performance hot swap controller with a PMBusTM pliant SMBus/I2C interface to accurately measure, protect and control the electrical operating conditions of systems connected to a backplane power bus. The LM5064 continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface. The LM5064 control block includes a unique...
