The Melexis US5782 is a unipolar Hall-effect switch designed in mixed signal CMOS technology.
The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver. All in a single package.
The wide operating voltage from 3.5V to 24V, "L" and "E" operating temperature and low current consumption make this device especially suitable for automotive and solid state switch applications.
The output signal is open-drain type. Such an output allows simple connectivity with TTL or CMOS logic by using a pull-up resistor tied between a pull-up voltage and the device output.
