    The LM25066A combines a high performance hot-swap controller with a PMBus ™ compliant SMBus/I 2C interface to accurately measure, protect and control the electrical operating conditions of computing and storage blades connected to a backplane power bus. The LM25066A continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface.

    The LM25066A 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 LM25066A interfaces with a low-cost external diode for monitoring the temperature of the external MOSFET or other thermally sensitive components. The POWER GOOD output provides a fast indicator when the input and/or output voltages are outside their programmed range. LM25066A current measurement accuracy is ±1% over temperature.

    The LM25066A monitoring block 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.
