TI to expand products with intelligent power monitoring and control for telecom, industrial and computing systems

DALLAS (June 22, 2009) - Texas Instruments announced today an agreement with Power-One, which expands the market for TI's analog and digital power management products that support the PMBusTM protocol. The non-exclusive Field of Use license agreement for Power-One’s digital power technology patents will benefit original equipment manufacturers who use TI’s point-of-load controllers and modules except for manufacturers of merchant power supplies.

TI offers several power management controllers that support PMBus, an open standard digital power communications interface that allows the configuring, control and monitoring of power systems. For example, the four-output, multi-phase UCD9240 and dual-output UCD9220 power system controllers are fully configurable via an easy-to-use graphical user interface (GUI) for monitoring, control and management for DC/DC point-of-load power conversion.

The PMBus standard specification, developed by a consortium of 40 power supply, telecommunications equipment and semiconductor providers, defines a digital communication protocol that enables power converters to be configured, monitored and maintained according to a set of more than 100 commands. PMBus provides increased reliability and system intelligence. Designers can set a power supply's operating parameters, monitor operation and perform corrective measures in response to faults or if the power shuts a system down.
