  • Patent number: 8981733
    Abstract: In one embodiment the present invention includes a system and method of charging a battery using a switching regulator. In one embodiment, a switching regulator receives an input voltage and input current. The output of the switching regulator is coupled to a battery to be charged. The switching regulator provides a current into the battery that is larger than the current into the switching regulator. As the voltage on the battery increases, the current provided by the switching regulator is reduced. The present invention may be implemented using either analog or digital techniques for reducing the current into the battery as the battery voltage increases.

  • Patent number: 8896272
    Abstract: Embodiments of the present invention include electronic circuits, systems, and methods for charging a battery. In one embodiment, the present invention includes a method, which may be implemented by an integrated circuit, comprising charging the battery using a constant current until the voltage on the battery increases to a first voltage level, and charging the battery using a constant voltage, wherein the constant voltage is set to a second voltage level. The constant current charging transitions to constant voltage charging when the voltage on the battery reaches the first voltage level, where the first voltage level is greater than the second voltage level.

  • Patent number: 8436936
    Abstract: Embodiments of the present invention include circuits and methods for calibrating position displacement in a voltage controlled actuator. In one embodiment, a calibration circuit comprises an actuator having a control terminal for receiving a programmable control voltage to set a displacement, a switch that selectively decouples said programmable voltage from said control terminal and couples a reference current to said control terminal when the control terminal is decoupled from said control voltage, a comparator that senses a voltage difference between said control voltage and said control terminal, and a timer coupled to an output of the comparator. The timer measures a time period required to increase the control terminal voltage. The capacitance of the actuator may be determined and used to calibrate the position of the actuator.
