The LM5064 combines a high performance hot swap controller with a PMBusTM compliant 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 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. The input under-voltage and over-voltage levels and hysteresis are configurable, as well as the insertion delay time and fault detection time. A temperature monitoring block on the LM5064 interfaces with a low-cost external diode for monitoring the temperature of the external MOSFET or other thermally sensitive components. The PGD output provides a fast indicator when the input and/or output voltages are outside their programmed ranges.

The LM5064 monitoring circuit computes both the real-time and average values of subsystem operating parameters (VIN, IIN, PIN, VOUT) as well as the peak power. Accurate power averaging is accomplished by averaging the product of the input voltage and current. A black box (Telemetry/Fault Snapshot) function captures and stores telemetry data and device status in the event of a warning or a fault.
