2. Technical Description:

SC9641 detects the trajectory of ferromagnetic and permanent magnets by measuring the flux density of the magnetic field. The correction range of magnetic offset can reach ± 20mT, and the device offset can be eliminated by self-calibration algorithm. The on-off state of the chip is indicated by high current consumption and low current consumption. High precision, high sensitivity, wide temperature range, high ESD and EMC robustness make the chip suitable for demanding automotive electronic applications.

3. Unique advantages：

Dynamic self-correction technology; Anti-electromagnetic interference technology at the output end; Ultra-thin packaging technology; It can replace the products of the same type of foreign manufacturers, such as Infineon TLE4941plusC; Allegro A19200/A1642/A1684.

4. Application Scenarios：

ABS wheel speed, gearbox

Enterprise Future Development Prospect

Semiment products can seamlessly replace similar products from foreign manufacturers, and have been deployed in most Tier1 for more years; Semiment owns reliable products and controllable delivery, and develop the next generation products to fill the gap; And cooperate with the auto OEM /Tier1 to improve security and cost performance.
