Potentia Debuts PS-1005/PS-1006 Power-Management ICs
Potentia Semiconductor (Ottawa, Ontario, Canada), a power management company, announced its PS-1005 and PS-1006 primary-side, power-management ICs that enable integration of primary-side and secondary-side power control schemes. With an on-chip serial data link, the PS-1005 and PS-1006 ICs are the first in a series of devices to comprehensively monitor and control the primary side of isolated power subsystems.
An on-chip, 10-bit, analog-to-digital converter digitizes status information and transmits to a companion IC on the secondary side. The integration of on-card primary-side and secondary-side power control schemes maximizes system uptime in networking and high-availability storage and computer power architectures. Residing on the high-voltage side of the safety isolation barrier, the PS-1000 Series devices continuously monitor primary input voltage, current and fuse status information. Digitized data is transmitted through the PI-Link interface to the secondary-side power-management controller. The primary-side status information is readily available via the I2C interface of the PS-2406.
The PS-1005 and PS-1006 are configured with under-voltage and over-voltage detection thresholds, which are used to shut down the card under adverse circuit conditions. Input voltage brownout detection is also provided by the ICs. Under-voltage, over-voltage and brownout alarms are communicated to the PS-2406 through the PI-Link interface, together with fuse status. As well as primary-side monitoring and control, the PS-1006 integrates inrush current limiting. By controlling an external MOSFET, the IC limits card inrush current at startup, enabling hot-swapping of cards without damaging the system or causing service disruption.
The new PS-1005 and PS-1006 are now available. The PS-1005 is priced at $4.60 in quantities of 10,000 units while the PS-1006 is priced at $6.60 for the same quantity.
