HX810 is a single-chip programmable Hall effect linear sensor produced using advanced BCD technology. It includes a high-sensitivity Hall sensor, high-precision Hall temperature compensation unit, Hall signal preamplifier, oscillator, dynamic offset elimination circuit, and amplifier output module. It can provide customers with more effective AC/DC current detection solutions and is widely used in communication, industrial, and consumer electronic devices.
HX810 adopts overcurrent protection and high bandwidth dynamic offset cancellation technology. In the absence of a magnetic field, the static output can choose 50% VCC or a fixed value of 2.5V. The internally integrated dynamic offset elimination circuit ensures that the sensitivity of the IC is not affected by external pressure and IC packaging stress.
The output voltage of HX810 is directly proportional to the applied magnetic field strength. Users can program the power pins to adjust the chip sensitivity and static (zero field) output voltage, thereby improving product performance in the final application.
The static output voltage of HX810 can be adjusted within a range of 2.5V ± 0.2V or 50% VCC, and the output sensitivity can be adjusted within a range of 1.8-30mV/Gs.
