The CYD8536 a dual-channel, bipolar switch with two Hall Effect sensing elements, each providing a separate digital output for rotational speed measurement and direction detection. The Hall elements are photolithogrphically aligned to better than 1µm. Maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encounted in fine-pitch detection applications. The CYD8536 is a highly sensitive, temperature stable magnetic sensing device, which is ideal for use in ring magnet based speed and direction systems located in harsh automotive and uíndustrial environments.
The Hall elements of the sensor CYD8536 are spaced 1.6mm apart, which provides excellent speed and direction information for small-geometric targets. Extremely low-drift amplifiers guarantee symmetry between the switches to maintain signal quadrature. An on-chip regulator allows the use of this device over a wide operating voltage range of 2.8V to 24V.
The CYD8536 is available in a 4-pin SIP package. The package is lead (Pb) free, with 100% matte tin leadframe plating.
