High-precision angle position sensor
11 June 2008, Test & Measurement

austriamicrosystems has expanded its successful magnetic rotary encoder family with the AS5134. This IC is fully qualified to AEC-Q100 and specifically designed for brushless DC sensing in automotive applications in an ambient temperature range up to 150°C. With an 8,5-bit resolution, the AS5134 can recognise 360 positions within one 360° turn and is accessible with either a serial or a PWM (pulse-width modulation) interface. In addition, there are three differently programmable incremental outputs available, one of which delivers a three-phase commutation signal for brushless DC motors. Another special feature is the programmability of one to six pole pairs. The AS5134 provides a 'power saving mode' with a power consumption of less than 1,5 mA and a fast start-up time to normal operation of less than 250 μs. Several features of the AS5134, including user-specific zero programming, a diagnostic function for correct positioning of the magnet, and the ability to recognise interruptions of the power supply are standard functions. The AS5134 additionally offers a 'daisy chain' mode to read position data serially over a two wire bus.
