Potentia Unveils PS-2607 Power System Controller
Potentia Semiconductor Corp. (Ottawa, Ontario, Canada) unveiled its new PS-2607 power system controller, which features an embedded fault log that records the last 14 power system faults in an integrated EEPROM and provides quick identification of 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-packaged PS-2607 offers digitally configurable power management of up to six non-isolated dc-dc converters and an intermediate bus. The EEPROM also supports unlimited reprogrammability of device configuration registers.
With Potentia's PowerCenter Designer™ software, users can configure the controller to handle interlocked power rail sequencing for startup and shutdown, and to set trim values, over-voltage and under-voltage 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 interface makes secondary-side power system data available to system-level CPUs, and through its PI-Linkâ„¢ isolated communications interface, it can also provide voltage, fuse status, and fault data from the 48 V 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 power sequencing following a fault condition. The PS-2607's four general-purpose I/O pins offer additional flexibility and can be allocated as enable inputs, as power status flags, or as interrupts for over-voltage/under-voltage warnings, primary-side fault indication, or primary-side shutdown.
The PS-2607 power system controller is priced at $6.60 each in 10,000-piece quantities.
