The HXS21C is a current-output, latched Hall effect sensor based on a 60V BCD process platform, utilizing high-frequency chopping technology. It offers high magnetic field consistency and symmetry across its full operating voltage and temperature range. The integrated voltage regulator supports input voltages from 4V to 24V, making it suitable for industrial and automotive applications, while also providing strong electromagnetic interference (EMC) resistance and high reliability. The sensor incorporates dynamic offset cancellation and temperature compensation to minimize variations due to process, packaging, and thermal stress, ensuring stable sensitivity. It features an integrated voltage regulator, Hall array, amplifier, low-pass filter, hysteresis comparator, and output current control. The two-wire current output interface simplifies wiring and facilitates open/short circuit diagnostics. Available in 3-pin TO-92S (UA) and 3-pin SOT23-3L (SO) packages, both with 100% lead-free matte tin-plated leads.
