Bluetooth headset with unipolar micro-power Hall switch AR211

The high-sensitivity Hall switch 6207 is a micro-power, high-sensitivity omnipolar Hall switch sensor with latch output, which can directly replace traditional reed switches. It is particularly suitable for battery-powered portable electronic products, such as mobile phones, cordless phones, notebook computers, PDAs, etc.

The 6207 features omnipolar magnetic field discrimination, meaning it can be activated by either the north or south magnetic pole approaching, and the output turns off once the magnetic field is removed. Unlike other conventional Hall sensors, it does not require a specific south or north pole to operate, reducing the hassle of identifying magnetic poles during assembly. The internal circuit includes a Hall slice, voltage regulator module, signal amplification processing module, dynamic offset cancellation module, latch module, and CMOS output stage. Thanks to the advanced Bi-CMOS process, the optimized circuit structure ensures extremely low input error feedback. The product employs dynamic offset cancellation technology, which eliminates offset voltage caused by packaging stress, thermal stress, and temperature gradients, improving device consistency. Additionally, the product utilizes a highly miniaturized packaging process, giving it superior performance and market advantages.
