Device for limiting the capacitance charging current, charge pump arrangement, method for limiting a charging current at a charge pump and method for limiting the charging current at a capacitor

摘要

A device limits a capacitance charging current. The device has a differentiating device that is coupled in parallel with a capacitance that is to be charged at a charging node. A switching device is connected to an output of the differentiating device. The switching device prevents a charging current—which is supplied to the capacitor—if a predetermined value is applied to the output of the differentiating device.
