Abstract
A device using a single external resistor for battery charging applications and a software current feedback control loop for use with the external resistor is described. For instance, a single resistor can be used to determine the charge electrical current level being used to charge a battery. The determined level from the single resistor can be used in a feedback loop to set the charge electrical current level and to determine if there is an over current condition requiring the charge current be shut down.
