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

Intersil Corporation 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

* 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

The ISL6146 is available now in 8-lead MSOP and DFN packages, with prices starting at $1.20 each in 1,000-unit quantities.
