Abstract: An apparatus, comprising: a first transmitting coil including at least one first portion and at least one second portion, the first and second portions having different polarities; and a second transmitting coil that is disposed above or below the first transmitting coil, the second transmitting coil including at least one third portion and at least one fourth portion, the third and fourth portions having different polarities, wherein the first and second transmitting coils are configured so that, when the first transmitting coil is not driven and the second transmitting coil is driven, a net magnetic flux through at least one of the first portions is approximately zero, the net magnetic flux being a magnetic flux that is entirely attributable to the second transmitting coil.

Abstract: In one aspect, a temperature detection circuit includes a first circuit configured to provide a first signal and a comparator circuit configured to provide a warning signal in response to the first signal if a temperature reaches a temperature value. The first signal enables determination of a parameter of a magnetic sensor.

Abstract: A method of detecting a vibration comprises determining a vibration flag has been set during a running mode of the magnetic field sensor, remaining in the running mode until a predetermined number of vibration flags have been set, and entering a recalibration mode when the predetermined number of vibration flags have been set. A counter can be implemented for each of the plurality of vibration flags to determine if the predetermined number of vibration flags have been set.

Abstract: A method of detecting a vibration comprises determining a vibration flag has been set during a running mode, entering a vibration mode, providing direction information for a target object during the vibration mode of the magnetic field sensor, holding onto positive peak values and negative peak values of the magnetic field signal during the vibration mode of the magnetic field sensor, and returning to the running mode after receiving at least two clock cycles of the magnetic field signal with no further vibration flags set.
