30: ON Semi Announces New Power MOSFET for Automotive Modules
ON Semiconductor announced the introduction of six new AEC-Q101 qualified logic level, single channel, power MOSFETs for automotive module in small, flat lead packages. Offered in a 5 x 6mm SO-8FL package and a 3.3 x 3.3mm WDFN-8 package, these devices use 50% or less of the footprint of industry standard DPAK packages, yet offer the same or lower ’on’ resistance. The devices save valuable board space versus established DPAK packaged parts and are ideal for load switching, dc-dc conversion, and power management in automotive applications such as fuel injection systems and motor control drivers.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
