摘要： An integrated circuit current sensor includes a lead frame having at least two leads coupled to provide a current conductor portion, and substrate having a first surface in which is disposed one or more magnetic field transducers, with the first surface being proximate the current conductor portion and a second surface distal from the current conductor portion. In one particular embodiment, the substrate is disposed having the first surface of the substrate above the current conductor portion and the second surface of the substrate above the first surface. In this particular embodiment, the substrate is oriented upside-down in the integrated circuit relative to a conventional orientation. A current conductor portion can be deposited proximate to a surface of the substrate and proximate to the one or more magnetic field sensors. With this arrangement, a current sensor is provided for which the one or more magnetic field transducers are very close to the current conductor portion, resulting in a current sensor having improved sensitivity. An insulating layer can be disposed between the current conductor portion and the substrate.

摘要： An apparatus for driving a motor comprises a drive signal generation circuit configured to produce pulses on a pulse-width modulated drive signal in response to a control signal. A detection circuit is coupled to receive a commutation signal from the motor to monitor the speed of the motor. A control signal generation circuit is configured to dynamically generate the control signal so that a frequency of pulse-width modulated drive signal corresponds with the duration of the phase of the motor, so as to reduce the occurrence of an incomplete pulse on the drive signal. Methods for driving a motor are also disclosed.

摘要： Presented is a sensor that includes a magnetoresistive (MR) sensing device to sense a magnetic field and to produce an AC signal voltage proportional to the sensed magnetic field. The sensor also includes circuitry, coupled to the MR sensing device, to remove DC offset from the AC signal voltage. The DC offset may be related to the hysteresis characteristics of the MR sensing device. To remove DC offset, the circuitry may obtain an averaged DC offset and subtract the averaged DC offset from the AC signal voltage to produce a sensor output signal.
