Texas Instruments LM5064 Negative Voltage System Power Management and Protection IC with PMBus
Texas Instruments LM5064 Negative Voltage System Power Management and Protection IC with PMBus combines a high performance hot swap controller with a PMBus-compliant SMBus/I²C interface to accurately measure, protect, and control the electrical operating conditions of systems connected to a backplane power bus. TI LM5064 continuously supplies real-time power, voltage, current, temperature, and fault data to the system management host via the SMBus interface. The LM5064 Power Management and Protection IC control block includes a unique hot swap architecture that provides current and power limiting to protect sensitive circuitry during insertion of boards into a live system backplane, or any other "hot" power source. A fast acting circuit breaker prevents damage in the event of a short circuit on the output. TI LM5064 is ideal for use in a variety of applications, including base station power distribution systems, intelligent solid state circuit breakers, and more.
