SC9633 is a differential Hall Effect sensor IC with two independent channels providing quadrature outputs. The device provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. The integrated circuit is response to changing differential magnetic fields created by rotating ring magnets and by ferrous targets when coupled with a magnet. By use of the A/B quadrature outputs, the device is particularly suitable for speed and direction of magnetic ring or ferromagnetic toothed wheels.
The device is packaged in a 4-pin plastic SIP. It is lead (Pb) free, with 100% matte tin plated lead frame.
