HX6701 High Sensitivity, Quasi-Zero Power Magnetoresistive Sensor

The HX6701 is a magnetic switch sensor integrating Tunnel Magnetoresistance (TMR) technology and CMOS technology. It offers high precision, high speed, low power consumption, and high sensitivity, making it suitable for magnetic switch detection in industrial and consumer electronics. The internal circuitry includes a voltage generator, comparator, digital logic control module, threshold trimming module, and CMOS output circuit. The HX6701 features a wide operating voltage and temperature range, providing all-pole magnetic response with extremely low current consumption. It detects magnetic fields parallel to the chip package surface. When the magnetic field strength exceeds the operating point (BOP), the switch outputs a low level; when the magnetic field strength falls below the release point (BRP), the switch outputs a high level. The HX6701 operates within a temperature range of -40 to 125 and a supply voltage range of 1.8V to 5.5V, with an average current consumption of only 0.16A. Available in SOT-23 and TO-92S packages, both compliant with halogen-free standards.
