Product Description
Product Overview
The Magntek MT6501 is a next-generation absolute angle position sensor IC based on advanced Anisotropic Magnetoresistance (AMR) technology. It offers high-reliability non-contact angle measurement with a 0-360 detection range. The sensor integrates two pairs of AMR Wheatstone bridges and specialized signal processing circuits, enabling it to respond to directional changes in magnetic fields parallel to the chip surface, independent of field strength. This design reduces sensitivity to magnet manufacturing errors and installation tolerances. The MT6501 features overvoltage and overcurrent protection, programmable detection ranges and output curves, and offers selectable analog, PWM, and switch outputs. It supports 12-bit resolution for analog or PWM outputs and is available in SOP-8 and TSSOP-16 packages compliant with EU RoHS standards. Ideal for industrial and automotive applications such as throttle position detection, steering wheel angle sensing, and pedal position monitoring.
