摘要：Circuit allocation supplies current to digital computer circuit via at least onecontrol input. Computer circuits have one current to use in the range of several
milliamperes. Function in the voltage range known to one for example between 2 and 6volts is guaranteed. A buffer battery group between two supply lines (UB and GND) isused as a reference voltage. In order to recognize it when low voltage operating, thedirection of battery current is determined. This can be determined by the transistor (29)with the semiconductor diode (28) in the antiparallel with its emitter-base stage path.Buffer battery group can be charged by be used to detect the base emitter current ofthe transistor in the direction of battery current. Charging current can be limited to thecoupling resistance of circuit allocation. This can be a thermistor.
