Hall Element Application on Bluetooth Headset
Bluetooth headset is the application of Bluetooth technology in hands-free headset, so users can get rid of the original headphones troubled, more convenient to a variety of ways to easily call or entertainment.
Due to the unique properties of Hall devices (solid structure, small size, light weight, long life, easy installation, low power consumption) is far superior to the reed pipe, is also widely used in the Bluetooth headset industry. Because Bluetooth headset power saving, support for long time calls, low-cost features, which determines the choice of the Hall element requires energy saving, low cost, small size.
Hall components are mainly divided into unipolar Hall element, bipolar (latch) Hall element, linear Hall element, all-pole Hall element on the market.The one widely used in Bluetooth headset is unipolar low-power Hall switch consumption.
The main features are:
Noise protection, chopper stabilization technology, ultra-low voltage can reach as low as 1.65V，
High sensitivity, consistency and stability.
