2.1
The Low Power Hall IC Switch is comprised of a Hall probe, bias generator, compensation circuits, oscillator,
output latch and a n-channel open drain output transistor.
The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the
temperature behavior and reduce influence of 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 ensure highly 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 50µs (typical operating time) sets the output state after sequential questioning of
the switch points and latches it with the beginning of the following standby phase (max. 120ms). In the standby
phase the average current is typically reduced to 3.5µA. Because of the long standby time compared to the
operating time the overall averaged current is only slightly higher than the standby current. The output transistor
can sink up to 1 mA with a maximal saturation voltage V
