Potentia Launches PS‑2406 Power Subsystem Controller

Potentia Semiconductor Corp. (Ottawa, Ontario, Canada), a power-management company, announced its configurable PS‑2406 power subsystem controller IC, which provides comprehensive power management of up to four secondary-side dc-dc power converters and offers a serial data link to the company's range of primary-side power-management ICs.

The PS-2406's ability to monitor and act on power system information from both sides of the high-voltage isolation barrier enables designers to maximize system uptime in networking and high-availability computer and storage applications. The PS-2406 provides all the functionality required to sequence, monitor and trim customer-specified dc-dc power converters and to handle power system fault conditions.

Using the integral PI-Link isolated communications interface, the PS‑2406 can receive primary-side voltage, current and fuse status information from devices such as Potentia's PS-1006. In addition, in the event of an unrecoverable secondary-side fault, the PS-2406 can instruct the PS-1006 to shut down the intermediate bus dc-dc power converter, thereby protecting the card from any further damage.

The PS-2406 is now available at a price of $4.60 in quantities of 10,000 units.
