Two-Wire Self-Calibrating Differential Speed And Direction Sensor IC With Vibration Immunity

The ATS651LSH is a mechatronics component with an integrated Hall-effect Sensor IC and rare-earth pellet, providing an easy-to-use solution for speed and direction sensing applications. The solid thermoset molded plastic package contains a samarium cobalt pellet and a Hall-effect IC optimized to the magnetic circuit. This device has been designed specifically for high reliability in the harsh automotive environment. The IC employs patented algorithms for the special operational requirements of transmission applications. This two-wire device communicates the speed and direction of a ferromagnetic target via a pulse width modulation (PWM) output protocol. The innovative dual differential detector scheme uses three Hall elements and two separate signal processing channels. This provides greater reliability than conventional designs. Because only one of the channels controls switching, the same edge of each tooth is used for determining output signals, in both forward and reverse target rotation, with direction information available on the first magnetic edge after a direction change.
