All polar latching type  

Micropower Hall effect switch

Summary:

The HC6206 is a low-power, high-sensitivity, all-polar hall switch sensor with latch output that directly replaces conventional reed switches. Especially suitable for battery-powered portable electronic products, such as mobile phones, cordless phones, laptops, PDAs, etc.

HC6206 has magnetic field discrimination full polarity, that is, as long as the magnetic field is near the north or South Pole can be started, the magnetic field is removed, the output is turned off. Different from other hall sensors, it does not need a specific north or South Pole to operate, reducing the difficulty of identifying magnetic poles during assembly. The HC6206's internal circuitry contains Hall chips, a voltage regulator, a signal amplification and processing module, a dynamic imbalance cancellation module, a latch module, and a CMOS output stage. Due to the use of advanced BI-CMOS process, the overall optimized circuit structure of the HC6206 enables the product to achieve extremely low input error feedback. The product uses dynamic misalignment elimination technology, which eliminates misalignment voltage caused by package stress, thermal stress, and temperature gradient to improve device consistency. At the same time, the product adopts its miniaturized packaging process, making the product more high performance and market advantages. The HC6206 is available in SOT23-3L and TO-92S packages with operating temperatures ranging from -40 TO 150 ° C.
