APS12626 Datasheet | Allegro MicroSystems

Features AND BENEFITS - Flexible and easy-to-use sensor for motors/encoders - ISO 26262 / ASIL A functional safety pliance - 2D magnetic sensing via planar and vertical Hall elements - Quadrature independent of magnet pole pitch and air gap- no target optimization required - Works in almost any orientation to the target (XY, ZX, and ZY options) - Reduces accumulation of lost counts/pulses - System can restore correct state after power-cycling (-P option) - Dual outputs of quadrature or speed/direction signals - High magnetic sensitivity - Optimized for applications with regulated power rails - Operation from 2.8 to 5.5 V - Automotive grade/qualified per AEC-Q100 - TJ up to 175°C - Output short-circuit protection - Resistant to physical stress - Small size TYPICAL APPLICATIONS - Automotive - Motorized window - Power closures/actuators blinds - Electronic power steering - White goods - Seat/window/sunroof motors - Trunk/door/liftgate motors - Industrial motors/encoders - Garage door openers DESCRIPTION The APS12625 and APS12626 integrated circuits are dual ultrasensitive Hall-effect latches optimized for use with ring magnets. They feature both vertical and planar Hall elements with sensing axes that are orthogonal to one another, providing 90° of phase separation. This phase separation is inherently independent of magnet pole spacing and air gap. No target optimization is required, making them extremely flexible and easy to...
