When automotive engineers need a contactless sensor for measurements such as throttle position, pedal position and exhaust gas recirculation (EGR) position, Hall-effect technology is a frequent choice. With the HAR 24xy linear Hall-effect sensor family, Micronas integrates two automotive-qualified die into an ultra-thin (<1 mm) TSSOP14-1 package. The two stacked die enable high-precision redundant measurements and smaller magnet designs.
The first two products, the HAR 2425 and the HAR 2455, are designed to match the performance, diagnostic and safety requirements of demanding automotive and industrial applications. The HAR 2425 has an analog output and the HAR 2455 has a PWM output.
A development board and LabView based programming software are available to simplify design in..
