DESCRIPTION
The SC2546 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photolithographically aligned to better than 1um. Maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications. The SC2546 is a highly sensitivity, temperature stable magnetic sensing device ideal for use in ring magnet based, speed and direction systems located in harsh...
