Abstract
Method and apparatus for providing a motor controller/driver integrated circuit package having diagnostic processing of signal(s) from a magnetic field sensor positioned in relation to a motor. The sensor signal may have a first voltage range corresponding to a valid high state and a second voltage range corresponding to a valid low state. A diagnostic module can process the received signal from the magnetic field sensor to determine whether the received signal has a voltage level within the first or second voltage ranges. An output module may generate an output signal having a state based on the whether the received signal has a voltage level within the first or second voltage ranges.
