Problems solved by technology

These multiple systems are usually powered independently and have different requirements for power supply timing. Therefore, different power supply circuits need to be designed for each system, and when multiple power supply circuits or devices appear in the same product, there will be a problem of power utilization. Low power consumption, high equipment power consumption and high cost

Abstract

The invention relates to a multi-system power supply sequential control circuit, which comprises a first power supply module, a second power supply module and a delay switching circuit, the first power supply module is connected with a first load system and outputs a first level to the first load system. The second power supply module is connected with the input end of the delay switching circuitand outputs a second level to the delay switching circuit; the output end of the time-delay switching circuit is connected with the second load system, and after the first power supply module suppliespower for a period of time, the second power supply module supplies power. Through power supply multiplexing, redundant power supply circuits are omitted, so that the cost is greatly saved, and the power supply efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a multi-system power supply sequence control circuit. Background technique [0002] With more and more functions and higher integration of electronic devices, some electronic devices are currently equipped with multiple systems to achieve different functions. These multiple systems are usually powered independently and have different requirements for power supply timing. Therefore, different power supply circuits need to be designed for each system, and when multiple power supply circuits or devices appear in the same product, there will be a problem of power utilization. Low power consumption, high equipment power consumption and high cost. Contents of the invention [0003] Based on this, it is necessary to provide a multi-system power supply timing control circuit, which can save redundant power supply circuits through power supply multiplexing, thereby greatly ...
