Abstract: Embodiments described herein provides a battery charging circuit that boosts an input current and feeds the boosted input current to a battery for fast charging. Specifically, the battery charging circuit includes a low dropout regulator (LDO) for providing a voltage, a switch mode charger, coupled between the LDO and a battery, and a capacitor divider, coupled between the LDO and the battery, in parallel to the switch mode charger, for dividing the voltage outputted from the LDO by a factor.

Abstract: According to another embodiment, a system includes a driver circuit that drives a first output and a second output; a coil coupled between the first output and the second output such that the driver circuit drives current through the coil in response to control signals; and a programmable slew circuit coupled to the driver circuit. In some embodiments, a switch is coupled between the first output and the coil. In some embodiments an over-voltage protection circuit is coupled to protect the driver circuit.
