1 General Description

The AS5163 is a contactless magnetic angle position sensor for

accurate angular measurement over a full turn of 360º. 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 0.022º = 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 PWM signal or 12-bit

ratiometric analog output.

The AS5163 operates at a supply voltage of 5V and the supply and

output pins are protected against overvoltage up to +27V. In addition,

the supply pins are protected against reverse polarity up to -18V.
