The ZC290x are series of Hall-effect sensor ICs that feature with temperature stable Hall signalconditioning chains with background dynamic offset compensation, a comparator,configurable voltage references and an open-drain output stage.The on-chip Hall sensor converts the magnetic flux through the chip to Hall signal voltage.The internal comparator compares the voltage with the predefined reference voltage. Theopen-drain output transistor is then switched on and off accordingly
