Intersil Holding Introduces the HIP1011D Power Control IC

January 09, 2000 by Jeff Shepard

Intersil Holding Corp. (Palm Bay, FL) recently announced what it claims is the industry's first IC providing independent power control to two peripheral component interconnect hot-plug slots, the HIP1011D.

According to the company, the HIP1011D is designed to deliver independent two-slot control in a single IC, simplifying design, reducing component cost and increasing system availability. The features and functionality of two HIP1011As are integrated into a single chip, resulting in reduced layout complexity and board-space reduction, according to Intersil. The device provides power on/off for the four voltages on the peripheral component interconnect bus. It is also designed to ensure fault isolation, preventing a single defective load from dragging down the main systems power.

According to Intersil, the ability to soft-start load cards under live power conditions minimizes inrush current, keeping the system running during upgrades and servicing. Acting as an electronic circuit breaker for all four voltages, the HIP1011D provides over-current detection and protection for both slots. It is designed to detect and report under-voltage on the +3.3V, +5V and +12V outputs, helping eliminate system downtime. The HIP1011D also features integrated +/-12V control FETs, which are designed to save board space and associated mounting costs of MOSFETs, and four extra sense resistors. The small, outline package, 28-lead NB SSOP saves board space with the same footprint as a single HIP1011 in a SO-16.

"With the increasing popularity of the Internet and e-commerce, high availability and prevention of website outages is of paramount importance," said Romeo Estores of Intersil Product Marketing. "The HIP1011D helps deliver this availability while simplifying design and reducing cost in the areas of components, assembly, layout and board space. It is a high-volume, cost-effective way for our customers to offer hot-plug capability not only in enterprise class servers but in mid-range and low-end servers as well."

The HIP1011DCA, narrow body SSOP-28, is currently available. In quantities of 100 to 999 pieces, the device is $6.55 each. The HIP1011D is also available in tape and reel.
