摘要： Disclosed are advances in the arts with novel and useful current mode regulators. Circuits, systems, and methods for current mode regulation include a primary side for receiving an input signal and a secondary for outputting an output signal. A regulator spans the primary and secondary sides in a configuration by which the input signal may be rectified and thereafter provided to the output node as an output signal. A current monitor is provided at the output node for comparing the output signal to a reference. A communication link is included for providing feedback to the primary side of the regulator for use in regulating the signal.

摘要： The present invention relates to a motor drive system which comprises a fan controller circuit operable to generate a PWM control signal for control of a motor speed. The fan controller circuit comprises a current detection circuit and a motor speed determination circuit. The system further comprises a fan driver circuit operable to drive a motor at a duty cycle based on the PWM control signal from the fan controller circuit. The fan driver circuit comprises a current sink circuit operable to draw current from the PWM control signal when the PWM control signal is high and when the motor reaches a predetermined position. In the addition, the current detection circuit is operable to detect the current draw on the PWM control signal and provide an indication signal to the fan speed determination circuit associated with such detection. Further, the motor speed determination circuit is operable to determine the speed of the motor based upon a timing associated with successive current draw detections. The present invention also relates to a method of determining a motor speed which comprises driving a motor at a duty cycle dictated by a PWM control signal and detecting a predetermined rotor position of the motor. The method further comprises generating a current pulse based on the rotor position, wherein the current pulse is convolved with the PWM control signal, detecting the current pulse, and determining the motor speed using successive detected current pulses.

摘要： An internal circuitry protection scheme which protects on-IC circuitry when an external regulator voltage pin is shorted to a higher voltage. The circuit prevents damage to the on-die circuitry that is on the internal voltage rail, by clamping the received voltage, thereby eliminating the chance of damaging the on die circuitry. The circuit offers protection even if the voltage difference is large, but the difference remains small between the internal rail and the external regulated voltage under normal operation.

摘要： An ESD protection structure which includes, preferably a single semiconductor chip, a forward SCR for coupling across a source of potential and a reverse SCR for coupling across the same source of potential which is non-symmetrical to the forward SCR. The breakdown voltage of the forward SCR is different from the breakdown voltage of the reverse SCR. Each of the SCRs has a separate triggering mechanism. None of the anode, cathode and triggering elements of the forward SCR are common to the reverse SCR. A unidirectional device, preferably a Schottky diode, is disposed in the body of semiconductor material between the forward and reverse SCRs to prevent conduction from the body of semiconductor material when the source of potential across the SCRs is reversed.
