Austriamicrosystems - Optimal motion sensing solution for angle position systems

Based on patented stacked-die technology, a new dual-die automotive magnetic rotary encoder IC , the AS5215, has been unveiled by Austriamicrosystems. The device targets challenging safety applications such as electronic power steering systems.

"Micro controlled systems are increasingly used in automotive position sensing applications. In most of these systems, the microcontroller capacity is only partly used. The AS5215 has been specifically developed to provide a position sensing solution which leverages on this fact, and allows our customers to design the most cost efficient systems", said Andreas Pfingstl, product manager automotive encoders, Austriamicrosystems. "The AS5215 can be easily implemented in existing system architectures, providing high reliable contactless angle measurements, without a need to replace or modify proven electronic control units."

The amplitude of the output signal is programmable via sensitivity and gain settings. Due to its selectable output mode signals - raw, inverted or DC-referenced - the AS5215 can fit a variety of conventional motion sensing systems which require measurement redundancy for safety reasons.

Based on the company's patented stacked-die solution, the dual-die AS5215 provides 'excellent' phase matching and very low sensitivity drift over the full ambient temperature range of -40C to +150C. The AS5215 is available in a small TSSOP 14 package and operates at 5V supply. A single die rotary encoder IC version, AS5115, in a SSOP 16 package, will be available in October 2009, says the company.

New 16-Channel LED controller IC for LCD TV from Austriamicrosystems

The expansion of its portfolio of specialized LED drivers and controllers of the newest generation of LCD TV backlight, the AS3693B 16-channel LED controller IC bee announced by austriamicrosystems.

Innovation AS3693B LED controller IC helps build very flat LCD TV with the greatest possible contrast ratio, resulting in better image quality. The concept of external effects and patented technology for saving energy that actively regulates the power to reduce energy loss in the system. This makes it very flat screen models as possible and allows the creation of highly energy-efficient solutions TV. The AS3693B LED controller IC is specifically designed to synchronize with the picture perfect LCD and LED backlight unit to achieve so-called "control block graduation for exceptional image quality.

The AS3693B high precision LED controller IC manages 16 LED cinnamon, each with an accuracy of the current 0.5%. This is by far the best performance in the industry today, says the company. The high degree of accuracy possible is the exact color and control the brightness of the LCD backlight currently available. In addition, new features, such as hand PWM "create entirely new possibilities LED control different segments of the backlight unit.

"We developed the AS3693B, our latest LED backlighting solution, in close cooperation with our OEM partners in the LCD screen to the latest features, such as reverse PWM on the market as soon as possible. We are proud to the innovator's position in this booming market with new central concepts of economics and outstanding overall system performance, "said Markus Luidolt, marketing director of LED backlight drivers, austriamicrosystems.
