Abstract

The invention belongs to the technical field of circuits and provides a redundant backup power source, a chip and an electronic device. The redundant backup power source includes a first power source,a second power source, a pull-down resistor, a capacitor, and a triode. The output end of the first power source is connected to one end of the pull-down resistor and the collector of the triode. Theoutput end of the second power source is connected to the emitter of the triode. The collector of the triode is the output end of the redundant backup power source. The output voltage of the second power source is greater than the output voltage of the first power source. The capacitor is connected between the base of the triode and the pull-down resistor. According to the redundant backup powersource, the chip and the electronic device provided by the embodiment of the invention, the redundant backup second power source can be input into use in real time through the triode when necessary, and is automatically put out of use after the first power source is re-powered on, thereby solving the problem in the prior art that the use of the backup power source is delayed and the backup power source cannot be automatically put out of use.

Description

technical field [0001] The invention belongs to the technical field of circuits, and in particular relates to a redundant backup power supply, chip and electronic equipment. Background technique [0002] For many chips or devices that need to work continuously, in order to ensure the continuity of work, it is necessary to select a backup power supply for it, so that the work of the chip or device will not be affected when the common power supply fails. Some of the existing backup power supplies require manual input, and although some have the function of automatic input, there is always a delay in the input time. In addition, after the common power supply is restored, the existing backup power supply cannot be automatically withdrawn, which increases the workload for power supply operation and maintenance. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a redundant backup power supply, chip and electronic equipment to s...
