AS5163 Datasheet | Aurelia Microelettronica

Description The AS5163 is a contactless magnetic angle position sensor for accurate angular measurement over a full turn of 360°. A sub range can be programmed to achieve the best resolution for the application. It is a system-on-chip, bining integrated Hall elements, analog front end, digital signal processing and best in class automotive protection features in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.022° = 16384 positions per revolution. According to this resolution the adjustment of the application specific mechanical positions are possible. The angular output data is available over a 14 bit digital protocol, a 12 bit PWM signal or 12 bit ratiometric analog output. The AS5163 operates at a supply voltage of 5 V and the supply and output pins are protected against overvoltage up to +27 V. In addition the supply pins are protected against reverse polarity up to - 18 V. 2 The AS5163 Adapter board 2.1 Board description The AS5163 adapter board is a simple circuit allowing test and evaluation the rotary encoder quickly without building a test fixture or PCB. The PCB requires only a 3-wire connection: 5V power supply, GND and the output connection (KDOWN is optional). Only pin 1, 3, 5, and 7 of JP1 are connected. Capacitor C1 and C2 (both 2.2u F) is buffering the LDO outputs VDD3 and VDD5; C3 (1u F) is placed between VDD and GND. 4 x 2.6mm mounting holes AS5163 encoder JP1 connector (GND, power supply, output/interface) Figure 1: AS5163 Adapterboard Revision 1.0, June 2009 .austriamicrosystems.
