A sub range User programmable start and end point of the application region can be programmed to achieve the best resolution for the User programmable clamping levels and programming of the application. It is a system-on-chip, combining integrated Hall transition point elements, analog front-end, digital signal processing and best in class automotive protection features in a single device. Powerful analog output To measure the angle, only a simple two-pole magnet, rotating over - Short circuit monitor the center of the chip, is required. The magnet may be placed above - High driving capability for resistive and capacitive loads or below the IC. Wide temperature range: -40C to +150C The absolute angle measurement provides instant indication of the Small Pb-free package: 14-pin TSSOP magnets angular position with a resolution of 0.022 = 16384 Broken GND and VDD detection over a wide range of different positions per revolution. According to this resolution the adjustment load conditions 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. 3 Applications The AS5163 operates at a supply voltage of 5V and the supply and The AS5163 is ideal for automotive applications like Throttle and output pins are protected against overvoltage up to +27V. In addition, valve position sensing, Gearbox position sensor, Headlight position the supply pins are protected against reverse polarity up to -18V. control, Torque sensing, Pedal position sensing and non contact Potentiometers.
