Abstract
An integrated magnetic field sensor includes a magnetic field sensing element configured to generate a magnetic field sensing element output signal in response to a magnetic field. The integrated magnetic field sensor also includes a threshold control node configured to receive a control signal from outside of the integrated magnetic field sensor, wherein the integrated magnetic field sensor is configured to provide an adjustable threshold signal in response to the control signal. The integrated magnetic field sensor also includes a comparator having a first input node coupled to receive a first signal representative of the magnetic field sensing element output signal, a second input node coupled to receive a second signal representative of the adjustable threshold signal, and an output node at which is generated an output signal responsive to the first and second signals.
