Cross chip CC7031ST

The CC7031 is a micro- power, high sensitivity full- polarity, open- drain output magnetic sensing chip with both AMR magnetoresistive and Hall built- in. It is suitable for portable electronics that use batteries as a power source, as well as other low- power circuits. The CC7031 has an full- polarity magnetic field discrimination capability, which can be activated as long as the magnetic field north pole or south pole is close by, and the output turns off when the magnetic field is withdrawn, which reduces the hassle of identifying the magnetic poles during assembly. The internal circuitry of the CC7031 contains an AMR reluctance detection module, a Hall thin slice, a voltage regulator module, a signal amplification and processing module, a dynamic offset cancellation module, a latch module, and an open- drain output stage. As the CC7031 uses the advanced AMR+HALL principle, it is able to detect magnetic fields in both the X- and Z- axis directions. The product adopts dynamic offset cancellation technology, which eliminates offset voltages caused by package stresses, thermal stresses, and temperature gradients to improve device uniformity. At the same time, the product adopts its miniaturized packaging process, which makes the product have higher performance and market advantages. CC7031 is available in SOT23- 3 and TO- 92S package, The operating temperature is - 40~85°C
