1. General Description

This document describes the programming of the AS5x61 / AS5x62.
The AS5x61 / AS5x62 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, combining 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 12 bit ratiometric analog output.
The ASx61 / AS5x62 operates at a supply voltage of 5V and the supply and output pins are
protected against overvoltage up to +20V. In addition the supply pins are prote cted against
reverse polarity up to –20V.
