Intersil Introduces Industry's Most Robust ORing Controllers for Redundant Power

ISL6146 Series Provides Widest Voltage Range, Fastest Reverse Current Response

MILPITAS, CA--(Marketwire - Oct 4, 2012) -  Intersil Corporation (NASDAQ: ISIL), a leader in the design and manufacture of high-performance analog, mixed-signal and power management semiconductors, today introduced a robust, compact ORing FET controller that provides power redundancy and protection with minimal power dissipation.

The new ISL6146 works with N-channel power MOSFETs to increase power distribution efficiency when replacing a power ORing diode in high current applications. It can be used to provide an N+1 ORing power supply function, along with complete fault reporting for intelligent monitoring. 

The ISL6146 provides reverse current fault isolation with a 6A turn-off current, delivering the industry's fastest response to preempt potential damage to upstream components in cases of power loss. Measuring just 3mm x 3mm, it is the industry's smallest total solution and requires a minimum number of external components for power supply systems in infrastructure equipment applications.

Features and Specifications

  • Wide 3V to 20V bias and 1V to 20V operating voltage range support range of applications
  • ISL6146A and ISL6146B are optimized for very low voltage operation, down to 1V
  • Hot-swap transient rated to 24V to ensure reliability
  • Five options for various types of applications

Pricing and Availability
The ISL6146 is available now in 8-lead MSOP and DFN packages, with prices starting at $1.20 each in 1,000-unit quantities. For more information please visit:
