Austrian Microelectronics introduces fully redundant motion sensing IC AS5245 to meet the most stringent automotive safety requirements
Austrian Microelectronics today introduced the magnetic rotary encoder IC AS5245 with fault protection function, expanding its comprehensive magnetic rotary encoder product line. AS5245 is specifically designed to address stringent automotive requirements such as reliability, accuracy, and safety.
Andreas Pfingstl, Marketing Manager of the Automotive Encoder Division of Austrian Microelectronics, said: "Austria Microelectronics' new product AS5245 is designed to meet the requirements of applications such as pedals, gearboxes and steering wheels. If these applications fail, they may cause fatal dangers. .AS5245 motion sensor IC is based on the Austrian microelectronics industry's leading, proven stacked chip technology expertise. This technology meets the true redundancy requirements of safety-critical applications. AS5245 has built-in redundancy and on-chip diagnostics, which is more proactive Security trends. "
AS5245 is based on the stacked chip technology of Austrian Microelectronics, which can provide the best phase matching capability. No additional temperature compensation, calibration, or shielding from external interference magnetic fields are required. Customers will benefit from this most cost-effective solution for safety-critical systems.
To allow system designers greater flexibility in evaluation, the AS5245 can provide digital angle data through a simple serial interface or PWM signal. In addition, the incremental quadrature output mode with improved interpolation algorithm can be enabled and can be permanently programmed to 10 or 12-bit resolution.
The standard functions of Austrian Microelectronics' comprehensive encoder product line include user-specific zero programming, Chip-ID and diagnostic functions for correct positioning of the magnet. The AS5245's internal voltage regulator allows it to operate at a 3.3 V or 5 V supply voltage, and the operating ambient temperature can be as high as 150 ° C. AS5245 is available in lead-free, QFN 32 package.
