Abstract:
A method and system for detecting a charging current supplied to a portable device through a USB charger. The method includes the steps of connecting a charging circuit to a portable device, allowing the portable device to draw charging current from the charging circuit, measuring the current drawn from the charging circuit, comparing the measured current with a threshold value, making one or more system level decisions regarding charging of the portable device if the detected charging current is below the threshold current.
