Server power management IC compliant with Intel Node Manager 2.0

Texas Instruments has introduced a new server monitoring, protection and control IC with on-chip PMBus support. The LM25066IA is fully compliant to Intel Node Manager 2.0 and provides designers of servers with a system power management and protection solution that interfaces directly with the Intel management engine. The LM25066IA delivers 1-percent current measurement accuracy and 2-percent power measurement accuracy over the server operating temperature range.

TI's LM25066IA continuously supplies the system management host or management engine device with real-time power, voltage, current, temperature and fault data for each blade subsystem. The parametric and fault data is delivered through the system management bus (SMBus) communications interface using the industry-standard PMBus protocol and the host's system diagnostic and optimization routines use the data to limit the power to each blade subsystem, or node.

TI also offers the LM25066I that delivers 2.4-percent current measurement accuracy and 3-percent power measurement accuracy.
