STMicro Introduces Next-Gen High-Side Switches for Smaller, Smarter Automotive Electronics
STMicroelectronics has revealed the latest generation of its switch ICs for vehicle electronics such as lights and body modules. The new devices provide enhanced intelligent features, improve protection and reliability, and are up to 40% smaller than competing alternatives. In the seventh generation of ST's VIPower family, the M0-7 series of high-side switches, 75% of family members are available in a 5 x 4mm package, which is 40% smaller than the smallest competing devices. This allows car electronics designers to save pc-board space and aim for smaller module sizes.

Moreover, various internal design changes increase precision, enhance diagnostic feedback, and improve reliability. Specifically, performance improvements include greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
Intelligent high-side switches provide a more reliable and efficient replacement for conventional relays. For several generations, ST's VIPower family has offered advantages such as a common package style for many devices in the range. This allows tier-one suppliers to build several module variants using the same basic hardware and software so car makers can address differing requirements in international markets and offer various model specifications and options cost-effectively. The common-package approach has become widely adopted among high-side switch vendors.
Major features of M0-7 series: Precise load-current, voltage and temperature-monitor feedback; Integrated sense multiplexer; Power-limitation and over-temperature latch-off; Bulb / LED mode (quad channel); Flexible fault-reset management; Reverse-polarity protection; Full on- and off-state diagnostics capability; And ultra-low quiescent current.
Samples of all family members are available now. The first device to enter production will be the dual-channel VND7020AJ-E, in Q2 2013, priced from $1.10 for orders over 1,000 pieces. The full range of package types available across the new family will include PowerSSO-16, PowerSSO-36, Octapak, and SO-8.

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.
