Abstract

The merit of the connection is the functional use of PN transitions of the switching transistor (6) of the back-up battery (5) for connecting and disconnecting of this battery (5) to the backed-up circuit, automatically according to the difference between the supply voltage and voltage of the back-up battery (5). According to the solution, the power supply (1) is connected via the unidirectional diode (2) and transistor (6) of the type PNP to the positive electrode of the back-up battery (5), while one outlet of the resistance (4) is connected with the transistor base (6) and the line (32) for connection of the consuming apparatus (3) is arranged between the above-mentioned unidirectional diode (2) and negative electrode of the back-up battery (5). The resistance (4) is connected with its second outlet (42) to the line (32) between the consuming apparatus (3) and negative electrode of the back-up battery (5).<IMAGE>
