A19351 GMR Wheel Speed/Direction Sensor ICs

Allegro MicroSystems A19351 Giant Magnetoresistance (GMR) AK Protocol Wheel Speed/Direction Sensor Integrated Circuits (ICs) are designed to measure ring magnets used in automotive braking systems. A19351 ICs provide wheel speed and direction information. The fully integrated circuits feature sensing elements, voltage regulators, analog-to-digital converters, and a digital controller. These components adaptively measure the magnetic signal and provide a robust, low-jitter AK Protocol output across a two-wire interface.
