While the LM25066I/A is functionally similar to the LM25066/A, the LM25066I/A is fully compliant to Intel Node Manager 2.0, 2.5 and adds the READ_EIN energy accumulator feature. The LM25066I/A combines a high-performance hot-swap controller with a PMBus 1.2™ compliant SMBus/I2C interface to accurately measure, control and protect the electrical operating conditions of critical systems. The LM25066I/A continuously supplies real-time power, voltage, current, temperature, and fault data to the system management host via the SMBus interface.

The LM25066I/A control block includes a unique hot-swap architecture that provides current and power limiting to protect sensitive circuitry even during the most stressful conditions. A fast-acting circuit breaker prevents damage in the event of a short circuit on the output. The input under-voltage, over-voltage hysteresis, insertion delay time and fault detection time are all configurable. A temperature monitoring block on the LM25066I/A interfaces with a low-cost external diode for continuous temperature assessment of the external MOSFET or other thermal sensitive components. The POWER GOOD output provides a fast alert when the input and/or output voltages are outside their programmed range. Accurate power readings are accomplished by using the READ_EIN command. A black box (Telemetry/Fault Snapshot) function captures and stores telemetry data and device status in the event of a warning or a fault.
