high performance needs great design. Datasheet: AS5262 12-Bit Magnetic Angle Position Sensor Please be patient while we update our brand image as austriamicrosystems and TAOS are now ams. www.ams.com AS5262 12-Bit Magnetic Angle Position Sensor 1 General Description 2 Key Features 360 contactless high resolution angular position sensing The AS5262 is a contactless magnetic angle position sensor for accurate angular measurement over a full turn of 360. A sub range User programmable start and end point of the application region can be programmed to achieve the best resolution for the + linearization. application. It is a system-on-chip, combining integrated Hall User programmable clamping levels and programming of the elements, analog front end, digital signal processing and best in transition point. class automotive protection features in a single device. Powerful analog output 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 - Short circuit monitor or below the IC. - High driving capability for resistive and capacitive loads The absolute angle measurement provides instant indication of the Wide temperature range: - 40C to + 150C magnets angular position with a resolution of 0.022 = 16384 Small Pb-free package: MLF 16 6x6 (with dimple) positions per revolution. According to this resolution the adjustment of the application specific mechanical positions are possible. The Broken GND and VDD detection over a wide range of different angular output data is available over a 12 bit ratiometric analog load conditions. output. Saw tooth mode 1,2,3,4 slopes per revolution The AS5262 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 protected against reverse polarity up to 20V. 3 Benefits Figure 1. Typical Arrangement of AS5262 and magnet Unique fully differential patented solution Best protections for automotive applications Easy to program Additional linearization points for output characteristic Ideal for applications in harsh environments due to contactless position sensing Robust system, tolerant to magnet misalignment, air gap variations, temperature variations and external magnetic fields High inherent accuracy High driving capability of analog output (including diagnostics) Broken GND and VDD detection for all external load cases 4 Applications The AS5262 is ideal for automotive applications like throttle and valve position sensing, gearbox position sensor, tumble flap, chassis height level, pedal position sensing and contactless potentiometers. www.ams.com Revision 1.1 1 - 36
