Magnetic Rotary Encoder IC provides motion sensing.

Press Release Summary:

Based on stacked-die solution, dual die Model AS5215 provides analog sine and cosine output for redundant motion sensing in automotive microcontroller-based systems. Amplitude of output signal is programmable via sensitivity and gain settings. Users can select raw, inverted, or DC-referenced output mode signals. Housed in TSSOP 14 package, device operates at 5 V supply and offers minimal sensitivity drift over full ambient temperature range of -40 to +150°C.

austriamicrosystems' New Magnetic Rotary IC Provides an Optimal Motion Sensing Solution for Conventional Angle Position Systems

The AS5215, a new dual die, high precision analog sine and cosine output magnetic encoder IC targets redundant motion sensing solutions for automotive microcontroller-based systems

Unterpremstaetten, Austria (September 2, 2009) - austriamicrosystems (SIX: AMS), a leading global designer and manufacturer of high performance analog ICs for automotive, communication, industry and medical applications, today introduce the AS5215, a dual die automotive magnetic rotary encoder IC for safety challenging applications, such as electronic power steering systems. This solution is also based on austriamicrosystems patented stackeddie technology.

"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", says Andreas Pfingstl, Product Manager Automotive Encoders at 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 austriamicrosystems' patented stacked-die solution, the dual die AS5215 provides excellent phase matching and very low sensitivity drift over the full ambient temperature range of -40°C to +150°C. 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.
