Abstract: The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current.

Abstract: The disclosed embodiments provide a system that facilitates operation of a power adapter in hiccup mode. The system includes a bleeding mechanism that reduces a hiccup time of the hiccup mode by increasing a leakage current of the power adapter. The system also includes an activation mechanism that activates the bleeding mechanism upon detecting a voltage drop associated with the hiccup mode.
