Applications Information
Two-Wire Hall IC Interfacing
When voltage is applied to two-wire Hall effect ICs, current
flows within one of two narrow ranges. Any current level not
within these ranges indicates a fault condition.
The following table describes some of the possible output
conditions that can be monitored through the SENSE pins.
Figure 5 is a typical application using the A6850 with dual
Hall effect ICs.
