AS5262 12-Bit Magnetic Angle Position Sensor

The AS5262 is a contactless magnetic angle position sensor designed for precise angular measurement over a full 360 turn. It offers a system-on-chip solution integrating Hall elements, analog front end, digital signal processing, and automotive-grade protection features. The device requires a simple two-pole magnet for angle measurement, providing instant absolute angle indication with a resolution of 0.022 (16384 positions per revolution). Its analog output is ratiometric to VDD, and it operates at a 5V supply voltage with robust overvoltage and reverse polarity protection.

Key Benefits & Features

360 contactless high-resolution angular position sensing
Great flexibility on angular excursion
User programmable start and end point of the application region
Saw tooth mode (1-4 slopes per revolution)
Failure diagnostics (Broken GND and VDD detection)
High-resolution analog output ratiometric to VDD
Ideal for applications in harsh environments due to contactless position sensing
Wide temperature range: -40C to 150C
Stacked die redundant approach
Small Pb-free package: MLF 16 6x6 (with dimple)

Applications

Throttle and valve position sensing
Gearbox position sensor
Tumble flap
Chassis height level
Pedal position sensing
Contactless potentiometers
