All-polar micropower Hall effect switch

Summary:

The HC6203 is a low-power, high-sensitivity, all-polar hall switch sensor with latch output that directly replaces traditional reed switches. Especially suitable for battery-powered portable electronic products, such as mobile phones, cordless phones, laptops, PDAs, etc.

HC6203 has magnetic field discrimination full polarity, as long as the magnetic field near the north or South Pole can be started, the magnetic field is withdrawn, the output will be closed. Unlike regular Hall sensors, the HC6203 does not require a specific north or South Pole to operate, reducing the difficulty of identifying magnetic poles during assembly. The product uses dynamic misalignment elimination technology, which eliminates misalignment voltage caused by package stress, thermal stress, and temperature gradient to improve device consistency.

The HC6203 internal circuit consists of hall chip, voltage regulator module, signal amplification and processing module, dynamic imbalance cancellation module, latch module, and CMOS output stage. Due to the use of advanced BiCMOS process, the overall optimized circuit structure of HC6203 enables the product to have extremely low input error feedback. At the same time, the product adopts its miniaturized packaging process, making the product more high performance and market advantages.

The HC6203 is available in tSOT23-3L and TO-92S packages with operating temperatures ranging from -40 TO 150°C.
