Intersil's ISL6146 ORing FET controller for Redundant Power
News Release from:
Intersil
04 October 2012
Intersil have today announced the release of a new 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.
