High-side active ORing solutions

10 November 2010 Power Electronics / Power Management

Picor, a subsidiary of Vicor specialising in the design and development of high-performance power management solutions, announced two additions to its Cool-ORing active ORing product family.

Primarily intended for 12 V and 48 V high-side redundant bus applications, the PI2127 is a full-function active ORing solution and the PI2007 is a universal, high-speed, discrete active ORing controller. Both address a broad range of redundant intermediate bus requirements for high-availability systems such as servers, high-end computing, telecom and communications infrastructure systems.

The PI2127 is a complete high-density, full-function active ORing solution with an integrated high-speed ORing MOSFET controller and a very low on-state resistance MOSFET. Its internal MOSFET maintains an on-resistance as low as 8,5 mW, resulting in very high efficiency and low power loss in steady-state operation, while also achieving very fast turn-off (typically within 80 ns) during input power source fault conditions that cause reverse current flow. The PI2127 is a 60 V-rated solution that delivers up to 12 A over a wide range of operating temperature from -40°C to 140°C. In system-in-package format, it occupies a thermally enhanced 7 x 8 mm land grid array outline.

The PI2007 is designed for use with single or paralleled N-channel MOSFETs in redundant power system architectures. It is optimised for use in 12 V and 48 V high-side redundant power architectures, including systems with a wide range input voltage of 36 V to 75 V that are also required to operate during input voltage transients up to 100 V for 100 ms. It enables a low power loss solution with fast dynamic response to fault conditions, with 80 ns reverse current turn-off delay time and 4 A gate peak discharge current capability to turn off the MOSFET very quickly. The device also checks for shorted FETs at system power-up.

Both devices feature an internal charge pump for high-side applications, and provide a fault flag output during reverse current, excessive forward over-current and UVLO fault conditions. Pairing the PI2007 with Picor’s PI2003, which is optimised for low-side operation, enables a complete high-side/low-side chipset solution for wide-range 48 V telecom applications.
