Patent ID: 8604763

Claim:
A power delivery system comprising: a control block operative to receive power and, in response, deliver a current to a load; a sensing circuit operative to sense the current delivered to the load and to generate a sensed signal in response; a comparator operative to compare the sensed signal to a reference signal to generate a compare signal, said compare signal having a first value if the comparator detects that sensed signal is equal to or greater than the reference signal, said compare signal having a second value if the comparator detects that sensed signal is smaller than the reference signal; a one-shot timer generating a logic signal that transitions from a first logic state to a second logic state for a predefined time period in response to a first occurrence of the first value of the compare signal; a signal selector selecting a first current limit reference signal in response to the first logic state of the one-shot timer and a second current limit reference signal in response to the second logic state of the one-shot timer, said control block setting a first current limit for the current it delivers to the load in response to receiving the first current limit reference signal, and setting a second current limit for the current it delivers to the load in response to receiving the second current limit reference signal, said second current limit being higher than said first current limit.
