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 current limit circuits. Some current limit circuits may involve user programmable function. User programmable function may need accurate current limit detectors. One approach to improving resolution and accuracy of current limit detectors using a single resistive device is to magnify the operating current range. Various embodiments of the present invention include devices and methods for detecting pre-programmed current limits.
