Controller Adds Diagnostics to Simplify Power System Trouble Shooting.OTTAWA, Canada -- The PS-2607 power system controller from Potentia Semiconductor is the first of its kind to feature an embedded fault log. Recording the last 14 power system faults in an integrated EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. , the fault log provides quick identification the precise cause of a power system failure during product design or field failure analysis. For high reliability telecom and high-end server applications, the 48-pin QFP (Quad FlatPack) A square, surface mount chip package that has leads on all four sides and comes in several varieties. PQFP (Plastic QFP) may refer to all of the following QFP types. All quad flatpacks use gull-wing leads, except for the CQFP, which stick straight out. packaged PS-2607 offers digitally configurable power management of up to six non-isolated DC-DC DC-DC Direct Current to Direct Current (power conversion) converters and an intermediate bus. The EEPROM also supports unlimited reprogrammability of device configuration registers. With Potentia's PowerCenter Designer(TM) software, users can configure the controller to handle interlocked power rail sequencing for startup and shutdown, and to set trim values, overvoltage and undervoltage warning and fault thresholds for each power rail. Power system designs featuring any type and combination of DC-DC converter are supported by the PS-2607 and can be validated using Potentia's PowerCenter Emulation Platform. The controller's I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller interface makes secondary side power system data available to system-level CPUs, and through its unique PI-Link(TM) isolated communications interface, it can also provide voltage, fuse status and fault data from the 48V primary side via Potentia's PS-1000 series power management ICs. With a separate input dedicated to intermediate bus voltage monitoring, the controller provides the means to determine the health of the bus before initiating startup sequencing. The controller can also be configured to automatically retry re·try tr.v. re·tried , re·try·ing, re·tries To try again. Verb 1. retry - hear or try a court case anew rehear power sequencing following a fault condition. The PS-2607's four general purpose I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output pins offer additional flexibility and can be allocated as enable inputs, as power status flags or as interrupts for OV/UV warnings, primary side fault indication or primary side shutdown. The PS-2607 power system controller is priced at 6.60 USD USD In currencies, this is the abbreviation for the U.S. Dollar.
