Ottawa, Canada - Potentia Semiconductor's PS-1005 and PS-1006 monitor chips, along with the company's PS-2406 configurable subsystem controller integrate primary- and secondary-side power control to provide significant uptime advantages for 48-volt card level applications. It's the first such set of ICs designed for comprehensive and proactive input-to-output power management, according to Potentia.
The PS-1005 (the PS-1006 adds inrush protection circuitry) monitors such primary-side parameters as voltage, current, and fuse state. The chip transmits system status across its digital PI-Link interface to the PS-2406 controller on the secondary side. Similarly, the PS-2406 instructs the PS-1005/1006 to shut down the intermediate bus (isolated DC/DC converter block) if there's an unrecoverable secondary-side fault.
The PS-2406, the first with a serial data link to the company's primary-side ICs, coordinates monitoring and managing of up to four secondary-side DC/DC converters (POLs). It also controls trimming, sequencing, and fault-handling (including system restart) functions. Configuration data is stored in the PS-2406's NVRAM via its (2-wire) I2C CPU interface or JTAG port. An optional EEPROM can be added for in-the-field rewriting capability. Users configure under-voltage and over-voltage levels, startup and shutdown thresholds, sequencing delay and trim values with the company's PowerCenter Designer software. Users validate hardware designs under live load, using the customer's choice of DC/DC power converters, with the company's PowerCenter Emulation Platform.
The PS-1005 is priced at $4.60 each, the PS-1006 is $6.60, and the PS-2406 (48-pin QFP package) is $4.60, all in 10k units.
