Product Description
The HX6388 is a programmable linear Hall sensor chip manufactured using BiCMOS technology. Its output voltage is directly proportional to the magnetic flux density. Programmable parameters include quiescent voltage, sensitivity, polarity, clamp voltage, and sensitivity temperature drift compensation, all adjustable by the user. The device features open-circuit, over-voltage, and under-voltage detection. Multiple HX6388 sensors can share a common bus, allowing individual calibration without interference. Programming is achieved by modulating the supply voltage, eliminating the need for an extra programming pin, which simplifies two-point calibration. The integrated temperature compensation circuit adjusts the output based on programmed temperature coefficients, enabling compatibility with most common magnetic materials and ensuring high accuracy across the entire temperature range. Designed for harsh industrial and automotive environments, the HX6388 operates typically at 5V and a temperature range of -40 to 150. It is available in compact SIP3-UA and SOP8-SO packages.
