Abstract: Systems and methods for overcurrent protection in a battery charger are provided. For example, a method for overcurrent protection may include controlling a switching regulator to direct electrical current between the switching regulator and a battery port; sensing a voltage drop that is related to the electrical current passing between the switching regulator and the battery port; applying a first ramp voltage to the sensed voltage drop generating a modified sensed voltage drop; comparing the modified sensed voltage drop against at least one reference voltage; and when the modified sensed voltage drop exceeds the at least one reference voltage, changing operation of the switching regulator to protect the battery charger from an overcurrent state.

Abstract: Systems and methods are provided for overcurrent protection in a battery charger. In certain embodiments, a method includes turning on an adapter switch to receive electrical power from an adapter connected to the battery charger; controlling a switching regulator to direct electrical current between the switching regulator and a battery port.

Abstract: A structure and process for a gouge-free substrate non-volatile memory cell with a floating gate, field effect transistor and a select gate transistor. The cell includes a floating gate, field effect transistor and a select gate transistor wherein the select gate transistor comprises a first conductive layer covered by a second conductive layer wherein electrical contact is made to the first conductive layer. The invention contemplates that the first and second conductive layers can be separated by an insulative layer. The invention also contemplates that the first and second conductive layers may be of different cross-sectional areas, wherein the cross-sectional area of the first conductive layer is larger than the cross-sectional area of the second conductive layer and wherein electrical contact is made to the first conductive layer at a sight not encompassed or covered by the second conductive layer.
