A method for operating a high vehicle circuit for a bandgap reference circuit, the method for assisting the run-up of a bandgap reference circuit and electronic circuit for carrying out the method

摘要

A method for operating a high vehicle circuit (22) for a bandgap reference circuit (1) with at least one in each case a diodes half conductor (d1, d2) comprehensive diodes branch, where the criterion for switching off of the high side of the circuit (22) the reaching of a predetermined difference voltage within the bandgap reference circuit (1) is arranged between a potential of a node (b1, b2) in the at least one diodes branch and a further node (b0), which is a potential proportional to the output voltage (vout) or proportional to the output current of the bandgap reference circuit (1) comprises.
