The LM25066IA provides designers of servers with a system power management and protection solution that interfaces directly with the Intel management engine.

The device 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.

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. The device 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 +80 V and -80 V applications respectively, and the LM25056, LM25056A and LM5056 for up to 17 V and 80 V applications respectively.

Availability and Pricing

The LM25066IA and LM25066I are offered in a 4-mm by 5-mm, 24-lead LLP package and are priced at US$2.95 and US$2.45 respectively, in 1,000-unit quantities.  The LM25066IA and LM25066I are sampling now with full production volumes scheduled for October 2012.
