Abstract: A device includes a battery current sense circuit configured to generate a battery current feedback voltage based on a current provided to a battery, a current regulation feedback loop configured to regulate the current provided to the battery based on the battery current feedback voltage and a configurable battery current reference voltage, and a precharge regulation feedback loop configured to regulate the current provided to the battery based on the battery current feedback voltage and a configurable precharge reference voltage. The device also includes a processor configured to set the battery current reference voltage to a first value and set the precharge current reference voltage to a second value. The first value is less than the second value during a transition state.

Abstract: A system that can include a detector that can monitor a voltage at an input of a transistor device over a period of time and provide a signal having a value representative of a capacitance between the input and an output of the transistor device. The system can further include a driver that can have a programmable drive strength and be coupled to input of the transistor device to drive the transistor device at the input thereof. The system can further include a controller that can configure the driver based on the signal to drive the transistor device with a corresponding drive strength.
