Battery Charger Short Circuit Monitor

摘要

Various apparatuses and methods for supplying an electrical current are disclosed herein. For example, some embodiments provide an apparatus including a current regulation switch connected in a current path between a power input and a current output. A current regulator is connected to the current regulation switch. The current regulator includes a current set terminal, and the current through the current regulation switch is proportional to the current through current set terminal. An impedance monitor is connected to the current set terminal.
