Hall Switch
MEMSIC's Hall switch sensors use a low-power CMOS process and integrate Hall sensor chip in a single chip. Built-in sensitivity compensation, and has excellent temperature compensation characteristics, so that the chip can work in the environment of -45 ~ 85 ℃, and maintain good performance and consistency.
Technical Advantages
Ultra-low Power
Typical 2.5uA, maximum 5uA@1.8 V, it can meet the needs of TWS ultra-long standby time
Ultra-wide Operation Voltage Range
Ultra-wide operation voltage range: 1.65~5.5V, which can meet the requirements of different supply voltages
Small Packaging
DFN4 package with 1.0mmx1.4mmx0.37mm, the smaller package size brings convenience to the structural design of the earphone and charging compartment. Also available in SOT23 and SOT553 packages
Accurate Switch Control
The hysteresis window is 5Gauss, that can ensure the opening and closing positions of the cover for the charging compartment being the same
Multiple Output Modes
Unipolar, bipolar and omni-polar Hall Switch can fit for different applications
