2D magnetic induction micropower magnetic sensor switch

Summary:

Hc7030/7031 is a micropower, high-sensitivity, all-polar magnetic sensor chip with both AMR reluctance and Hall, and with latch output, which can directly replace traditional reed switches. Suitable for portable electronic products using batteries as power supply and other low power circuits.

Hc7030/7031 has full polarity magnetic field discrimination ability, as long as the magnetic field is near the north or South Pole can be started, after the magnetic field is withdrawn, the output will be closed, reducing the trouble of identifying magnetic poles during assembly.

The internal circuit includes AMR reluctance detection module, Hall chip, voltage regulator module, signal amplification and processing module, dynamic imbalance elimination module, latch module and CMOS output stage. Because hC7030/7031 uses the advanced AMR+HALL principle, it is able to detect magnetic fields in both the X and Z axes. The product uses dynamic misalignment elimination technology, which eliminates misalignment voltage caused by package stress, thermal stress, and temperature gradient to improve device consistency. At the same time, the product adopts its miniaturized packaging process, making the product more high performance and market advantages.

The HC7030 is available in 3-pin SOT23-3L and TO-92S packages with operating temperatures ranging from -40 TO 85 ° C.
