Mfr. Part #:
AS5262-HMFP
Package:
QFN-16-EP(6x6)
Key Attributes
Model Number:
AS5262-HMFP
Product Description
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
