Micro power design? High sensitivity and high stability of the magnetic switching points? High resistance to mechanical stress? Digital output signal? Precise magnetic switching points and high temperature stability are achieved through the unique design of the internal circuit. An onboard clock scheme is used to reduce the average operating current of the IC. During the operate phase the IC compares the actual magnetic field detected with the internally compensated switching points.
The output Q is switched at the end of each operating phase. During the Stand-by phase the output stage is latched and the current consumption of the device reduced to some?
The IC switching behaviour is Omnipolar, i. The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the temperature behavior and reduce technology variations. The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall probe caused by molding and soldering processes and other thermal stresses in the package.
This chopper technique together with the threshold generator and the comparator ensures high accurate magnetic switching points. Very low power consumption is achieved with a timing scheme controlled by an oscillator and a sequencer. This circuitry activates the sensor for 50? In the standby phase the average current is reduced to typical 4? Because of the long standby time compared to the operating time the overall averaged current is only slightly higher than the standby current.
