    摘要： A magnetic field sensor includes a lead frame (310) having a plurality of leads (314, 316), at least two of which have a connection portion (334, 336) and a die attach portion (324, 326). A semiconductor die (340) is attached to the die attach portion of the at least two leads. The sensor further includes at least one wire bond (352) coupled between the die and a first surface (310a) of the lead frame. The die is attached to a second, opposing surface (310b) of the lead frame in a lead on chip configuration. In some embodiments, at least one passive component (360) is attached to the die attach portion of at least two leads.

    摘要： A monitor circuit for monitoring a level of a first and second regulated source may monitor a voltage level of regulated voltages or a current level of regulated currents. In an embodiment, the monitor circuit includes circuitry responsive to a first regulated voltage and to a second regulated voltage. A first circuit responsive to the first regulated voltage and to the second regulated voltage generates a first error signal indicative of at least one of an overvoltage condition of the first regulated voltage and an undervoltage condition of the second regulated voltage. A second circuit responsive to the first regulated voltage and to the second regulated voltage generates a second error signal indicative of at least one of an undervoltage condition of the first regulated voltage and an overvoltage condition of the second regulated voltage. A method for monitoring the levels of first and second regulated sources is also provided.

    摘要： A circuit to detect a movement of an object provides a threshold selection module or a peak identifier module that uses one or more threshold signals identified prior to a present cycle of magnetic field signal in order to establish a threshold signal used for a present cycle of the magnetic field signal. A method associated with the circuit is also described. The circuit and method can be tailored to store values associated with a least common multiple of a set of possible quantities of detectable features on target objects.
    An error processor may output an error signal in case that a current value of the peak related signal , e.g. a threshold a value derived from the peak signal, differs significantly from a value derived from stored samples recalled from positions corresponding to prior cycles which occurred an integer multiple of the least common multiple ago.
    An adjustment processor receives the error signal and adjusts the value of the least common multiple.
