October 8, 2012 – Intersil, a global leader in the design and production of high-performance analog and mixed-signal semiconductors, announced today the release of a powerful integrated O-ring FET controller that provides backup power while minimizing power loss.

The new ISL6146 can improve power distribution efficiency in conjunction with N-channel power MOSFETs when replacing power O-ring diodes in high-current applications. Additionally, it can be used to provide N+1 O-ring power supply capabilities, along with complete fault reporting for intelligent monitoring.

The ISL6146 isolates errors in reverse current with a 6A turn-off current that delivers a fast response to prevent potential damage to upstream components in the event of power loss. Measuring 3x3mm, it is the industry's smallest total solution and can operate with minimal external components for power supply systems within infrastructure equipment applications.

Features and specifications
• Supports a wide bias from 3V to 20V and an operating voltage range of 1V to 20V within the application.
• ISL6146A and ISL6146B are optimized to operate even at the lowest voltages, such as 1V.
• Adjust hot-swap transients to 24V to ensure reliability
• 5 options for various application types

Price and Usage Information
The ISL6146 is currently available in 8-lead MSOP or DFN packages, priced starting at $1.20 each for quantities of 1,000. Additional information is available at the following website: http://www.intersil.com/products/ISL6146
