Title:
CURRENT LIMIT CONTROL WITH CURRENT LIMIIT DETECTOR
Document Type and Number:
WIPO Patent Application WO2008046062
Kind Code:
A8
Abstract:
Devices, such as mobile devices, may be exposed to short circuit and output overload events. To protect against such events, mobile devices typically include circuitry to limit currents so as not to exceed a pre-programmed current limit. Various embodiments of the present invention include devices and methods for detecting pre-programmed current limits and for limiting currents in response to such detection. In some embodiments, both the current limit detector and the current limit controller circuitry include scaled current switches. The scaling may be substantially similar between the programmed-current limit detector and the current limit controller circuitry.
