Abstract
A controller configurable to operate in either in an NVDC mode or a standard mode. The controller includes mode logic that detects a mode value indicative of the selected mode and that asserts a corresponding mode signal, and control logic that is configured to operate according to the selected battery charging mode based on the mode signal and that provides a control signal accordingly. In the standard mode, the control signal is in either an on or off state depending upon presence of an external adapter and the charge state of the battery. In the NVDC mode, the control signal may operate in a linear mode if the battery is deeply discharged. A battery detector provides a battery indication that is used to switch the regulation operating point of an external system voltage. A power monitor output provides an indication of power being provided via the system voltage.
