Abstract
A method of determining an error condition in a magnetic field sensor can include receiving a first bridge signal, the first bridge signal generated by a first full bridge circuit. The method can also include receiving a second bridge signal, the second bridge signal generated by a second full bridge circuit. The method can also include determining a bridge separation from the first bridge signal and the second bridge signal. The method can also include comparing a function of the bridge separation to a threshold value. The method can also include generating an error signal indicative of the error condition or not indicative of the error condition in response to the comparing.
