摘要： An apparatus and method for controlling the common mode voltage across a data storage device write head. The write current is supplied by a first plurality of parallel current sources each independently activated to limit the common mode voltage generated across the write head. A plurality of parallel resistive elements responsive to current supplied by a second plurality of parallel current sources bias an output transistor that further controls the write current. Each of the plurality of parallel resistive elements and each of the second plurality of parallel current sources is also independently activated to limiting the common mode voltage generated across the write head.

摘要： A voltage regulator in a battery powered device, such as an implantable cardiac defibrillator, provides regulated output voltage for other circuits. When large currents are drawn from the battery, such as during charging of defibrillation output capacitors, switches decouple the regulator from receiving power from the battery and couple the regulator to receive power from a stable boost output voltage generated by a boost converter. The regulator provides a stable regulated output voltage less noisy than the boost output voltage. Controlled switch conductances in the regulator provide operation over a wide range of output load currents.

摘要： A level-shift circuit translates a control signal to a level-shifted output. The level-shift circuit includes a pulse generator circuit for providing Set and Reset pulses based on the control signal and a level-shift circuit for translating the Set and Reset pulses to level-shifted Set and Reset pulses. First and second differential detectors are connected to monitor the level-shifted Set and Reset pulses to provide detection of communicated Set and Reset pulses despite the presence of transients in the level-shift circuit. A gate drive circuit employs the Set and Reset pulses communicated by the differential detectors to generate a gate drive signal.

摘要： A pulse width modulation controller for a hard disc drive spindle motor controls the rapid spin up of the spindle motor from a stop condition to normal operating speed using a multi-level peak current limiting and six state commutation. At the beginning of each commutation state, peak motor current is limited to less than its steady state peak value for a selected number of pulses. The peak current target then returns its normal level for the remainder of the commutation state. By reducing the peak current target for several pulses after each commutation state change, the effective supply current spike at commutation is reduced or eliminated.

摘要： A motor controller for a three-phase spindle motor used in the hard disc drive provides pulse width modulated (PWM) signals used to drive the motor. The PWM signals have duty cycles which are a function of rotational position of the motor, a magnitude control signal, a stored set of main waveform coefficients, a stored set of modifier coefficients, and a modifier signal. By varying the modifier signal, the duty cycle of the PWM signals can be varied to adjust the shape of the motor current waveform to match the torque profile of the motor.

摘要： A method and apparatus for automatically adjusting the sensing threshold in an automatic implantable cardioverter/defibrillator with pacing capability. Fixed sensitivity is used for a specified interval following each pacing pulse and automatic sensitivity adjustment is used when spontaneous cardiac depolarization is detected. For spontaneous cardiac depolarization, the sensing threshold is automatically adjusted to a value proportional to the amplitude of the sensed cardiac signal. The sensing threshold continuously decreases between sensed cardiac depolarizations, ensuring that a lower level cardiac signal will be detected. When a pacing pulse is delivered, the sensing threshold is set to a fixed value and held at that value for a predetermined period of time such that the sensing threshold will not be affected by the cardiac response evoked by the pacing pulse. At the end of the predetermined period of time, the sensing threshold is decreased as it would following a spontaneous cardiac depolarization.
