TI Offers New 12-channel Sequencer & System Health Monitor With Power Supply Margining
Texas Instruments Inc. (TI) introduced a sequencer and system health monitor that features power supply margining and comprehensive non-volatile error logging, allowing customers to diagnose power supply failures in their systems.
The UCD90120 helps reduce board space by integrating 12 rails of sequencing; monitoring capability for up to 13 channels of voltage, current or temperature; and 10 channels of power supply margining. UCD90120 is designed for any system requiring sequencing and monitoring of multiple power rails including industrial, telecom infrastructure, servers and storage systems.
TI’s easy-to-use Fusion Digital Power Designer Graphical User Interface (GUI) allows the designer to configure the UCD90120 via a PMBus™/I²C interface. The free, downloadable tool simplifies the development process and improves time-to-market by allowing the designer to configure all device parameters in minutes.
Key features and benefits of the UCD90120 include: sequence and configure up to 12 channels, which allows flexible ramping up and down of multiple rails simultaneously; detect over- and under-voltage power supply warnings and faults and respond to these faults by configuring retries, shutdown delays and slave rail shutdowns. Failures are analyzed and logged via non-volatile error logging; margin up to 10 rails via PMBus to ensure power supply performance at upper and lower limits; and easily configure the design with the Fusion Digital Power Designer GUI to speed time to market.
The UCD90120 is available now in a 64-pin VQFN package, priced at $4.95 in quantities of 1,000. TI is also offering samples of UCD90124, which adds the ability to control and monitor up to four fans. Volume production of this device is expected in the fourth quarter.
