Server Power Management IC features on-chip PMBus(TM) support.

Press Release Summary:

Compliant to Intel® Node Manager 2.0, Model LM25066IA provides server designers with power management and protection solution that interfaces with Intel management engine. IC delivers 1% current measurement accuracy and 2% power measurement accuracy over server operating temperature. Parametric and fault data is delivered through SMBus communications interface using PMBus protocol, and host's system diagnostic and optimization routines use data to limit power to each blade subsystem, or node.


Original Press Release:

TI's PMBus(TM) Server Power Management and Protection IC Delivers Most Accurate Power Monitoring for Intel® Node Manager Capable Server Platforms

DALLAS, -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today 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, enabling these dynamic server platforms to implement power capping schemes that minimize operating expense and improve reliability in data centers. For more information and samples, visit www.ti.com/lm25066IA-pr.

TI's power management experts will demonstrate the LM25066IA in TI's booth #521 at the Intel Developer Forum in San Francisco, Calif., Sept. 11 to 13.

TI's LM25066IA integrates high-performance monitoring, protection and control blocks that precisely control and manage the electrical operating conditions of each blade in the chassis. It 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. Using this scheme, data center operators are able to minimize the overall power consumption of the server equipment while increasing system reliability by keeping the servers operating within their optimal operating power range.

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

The LM25066IA and LM25066I join TI's system protection and management family that includes the LM5066 and LM5064 for up to +80V and -80V applications respectively, and the LM25056, LM25056A and LM5056 for up to 17V and 80V applications respectively.

Key features and benefits of the LM25066IA PMBus server power management and protection IC

Power limiting allows the use of smaller, less expensive FETs while maintaining reliability.
Industry's best current and power measurement accuracy (one-percent and two-percent respectively) delivers up to three times more accurate power consumption data versus competitive solutions.
Simultaneous sampling of voltage and current allows measurement of true real-time power consumption under widely varying load conditions.
Energy accumulator reports total power consumed over a programmable time period.
