All-polar micropower Hall effect switch

Summary:

The HC6207/HC6207M is a low-power, high-sensitivity, all-polar Hall switch sensor with latch output that can directly replace traditional reed switches. Especially suitable for battery-powered portable electronic products, such as mobile phones, cordless phones, laptops, PDAs, etc.

HC6207/HC6207M has magnetic field discrimination full polarity, that is, as long as the magnetic field near the north or South Pole can be started, the magnetic field is withdrawn, the output will be closed. 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 HC6207/HC6207M internal circuit consists of Hall chip, voltage regulator module, signal amplification and processing module, dynamic imbalance cancellation module, latch module and CMOS output stage. Because HC6207/HC6207M uses advanced BiCMOS process, the overall optimized circuit structure enables the product to obtain 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 HC6207/HC6207M is available in SOT23-3L, TO-92S and DFN4L packages with operating temperatures ranging from -40 °C TO 125°C.
