Active ORing products target high-availability systems
Active ORing device offers 10x reduction in power dissipation compared to standard ORing designs
The Cool-ORing Family of active ORing solutions (PI2121, PI2122, PI2123, PI2125) and the discrete active ORing controllers (PI2001, PI2002, PI2003) target redundant power architectures such as servers, high-end computing and telecom, and communications infrastructure systems. The PI2121, PI2123, PI2125 devices integrate ORing MOSFET controllers and low on-state resistance MOSFETs. They provide a 10x reduction in power dissipation compared to standard ORing designs and have a 160-ns dynamic response.
The PI2121 is an 8-V, 24-A device suitable for ≤5-V bus applications, the PI2123 is a 15-V, 15-A solution suitable for ≤9.6-V bus applications and the PI2125 is a 30-V, 12-A design suitable for 12-V buses. The typical on-state resistances are 1.5, 3, and 5.5 mΩ, respectively.
The PI2001 is a discrete high-speed active ORing controller with similar functionality and feature set, for use with industry-standard single or paralleled MOSFETs. The PI2003 controller is optimized for use in 48-V redundant power architectures, and suits systems requiring operation during input voltage transients up to 100 V for 100 ms. The PI2122 has a circuit breaker and integrates a high-speed MOSFET controller and a low on-state resistance MOSFET. It is suitable for ≤5-V bus applications. The P12002, an active ORing controller IC with a load disconnect, is designed for use with back-to-back n-channel MOSFETs. (Ea/10,000: PI2121, PI2123, PI2125: $1.98; PI2122: $2.18; PI2001, PI2003: $0.84; PI2002: $0.92; available now.)
