Patent ID: 7672107

Claim:
A device for controlling current limits with a current limit detector, comprising: a current limit controller including a scaled transistor the scaled transistor adapted to drive a first current based on a control signal; a current limit detector adapted to detect a user-defined current limit and to activate the scaled transistor in response to the user-defined current limit; and a current limit portion including an amplifier adapted to generate the control signal, a large scale transistor of a predetermined large scale and a small scale transistor of a predetermined small scale, wherein a ratio between the predetermined large and small scales is preset to control a ratio between a small scale current and a large scale current flowing to the small and large scale transistors, respectively, the small and large scale currents switch being regulated by responsive to the control signal the amplifier generating the control signal by comparing the small scale current and the user-defined current limit, wherein the current limit controller includes a plurality of scaled transistors and wherein the output current includes a sum of currents flowing through the plurality of scaled transistors.
