AS5163
12-Bit Automotive Angle Position Sensor
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.

6.1 Operating Conditions
In this specification, all the defined tolerances for external components need to be assured over the whole operation conditions range and also
over lifetime.
TAMB = -40 to +150ºC, VDD = +4.5V to +5.5V, CLREG5 = 2.2µF, CLREG3 = 2.2µF, RPU = 1KΩ, RPD = 1KΩ to 5.6KΩ (Analog only), CLOAD =
0 to 42nF, RPUKDWN = 1KΩ to 5.6KΩ, CLOAD_KDWN = 0 to 42nF, unless otherwise specified. A positive current is intended to flow into the pin.

Figure 8 gives an overview of the different ranges. The failure bands are used to indicate a wrong operation of the AS5163. This can be caused
due to a broken supply line. By using the specified load resistors, the output level will remain in these bands during a fail. It is recommended to
set the clamping level CLL above the lower failure band and the clamping level CLH below the higher failure band.
