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. The AS5263 includes two AS5163 in one QFN package. transition point It is a system-on-chip, combining integrated Hall elements, analog Powerful analog output front-end, digital signal processing and best in class automotive protection features in a single device. - Short circuit monitor - High driving capability for resistive and capacitive loads To measure the angle, only a simple two-pole magnet, rotating over Wide temperature range: -40C to +150C the center of the chip, is required. The magnet may be placed above or below the IC. Small Pb-free package: 32-pin QFN (7x7mm) The absolute angle measurement provides instant indication of the Broken GND and VDD detection over a wide range of different magnets angular position with a resolution of 0.087 = 4096 load conditions positions per revolution. The start and end point of the sub segment Simplified programming due to provided programming hardware will be programmed with a resolution of 14-bit (0.022= 16384 steps and software per revolution). According to this resolution the adjustment of the application specific mechanical positions are possible. The angular Failure detection mode for magnet placement monitoring and output data is available over a 12-bit PWM signal or 12-bit ratiometric loss of power supply analog output. Indication of high voltage condition An internal voltage regulator with over voltage protection and reverse polarity protection allows the AS5263 to operate in automotive 3 Applications application up to a voltage to 27V. Programmability over the output pin reduces the number of pins on the application connector. The The AS5263 is ideal for automotive applications like transmission AS5263 is the ideal solution for safety critical applications due to the gearbox position sensor, headlight position control, torque sensing, redundant approach. valve position sensing, pedal position sensing, throttle position sensing, and non-contact potentiometers.
