It is a system-on-chip, Two digital 8-bit absolute outputs: combining integrated Hall elements, analog front end and digital - Serial interface signal processing in a single device. The angle can be measured using only a simple two-pole magnet rotating over the center of the - Pulse width modulated (PWM) output chip. The magnet may be placed above or below the IC. The User programmable zero position absolute angle measurement provides instant indication of the High speed: up to 30000 rpm magnets angular position with a resolution of 8 bit = 256 positions Failure detection mode for magnet placement monitoring and per revolution. This digital data is available as a serial bit stream and loss of power supply as a PWM signal. The AS5130 can be operated in pulsed mode (Vsupply=off), which reduces the average power consumption Wide temperature range: -40C to +125C significantly. During Vsupply=off, the measured angle can be stored Multi Turn counter / Movement detection using an internal storage register supplied by a low power voltage line. This mode achieves very low power consumption during polling Small Pb-free package: SSOP-16 (5.3mm x 6.2mm) of the rotary position of the magnet. If the position of the magnet Automotive qualified to AEC-Q100, grade 1 changes, then the motion detection feature wakes up an external system. The device is capable of counting the amount of magnet 3 Applications revolutions. The multi turn counter value is stored in a register and can be read in addition to the angle information. Furthermore, any The AS5130 is an ideal solution for Ignition key position sensing, arbitrary position can be set as zero-position. The system is tolerant Steering wheel position sensing, Transmission gearbox encoder, to misalignment, air gap variations, temperature variations and Front panel rotary switches and replacement of Potentiometers. external magnetic fields and high reliability due to non-contact sensing.
