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
