DESCRIPTION
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.
