Intersil Corporation has 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. The device 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 include: a wide 3V to 20V bias and 1V to 20V operating voltage range support range of applications; the ISL6146A and ISL6146B have been optimised for very low voltage operation, down to 1V; hot-swap transient rated to 24V to ensure reliability and there are five options for various types of applications.
