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
