Abstract

The invention relates to a time sequence control circuit applied to power supplies. The circuit mainly solves the problem that existing time sequence control circuits are complex. The circuit includesa timing circuit body and an enabling circuit body. A switched-on power supply makes the timing circuit body work normally through a three-terminal voltage regulator; when a time value set by the circuit is reached, a timer outputs high level to trigger the enabling circuit body, and the enabling circuit body controls an enabling end of a delay output power supply for output. The time sequence control circuit is simple in structure and reliable and can be applied to the multi-path power supplies.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a timing control circuit for power supply applications. Background technique [0002] With the development of electronic technology, there are more and more requirements for power supply for various logic circuits. Many systems expect the power supply to supply power according to a certain power-up sequence. [0003] In the existing power-on sequence control circuit, the peripheral circuit is complicated and many components are used, resulting in increased cost and low reliability. Therefore, a highly practical power-on sequence control circuit is the problem to be solved by the present invention. Contents of the invention [0004] technical problem to be solved [0005] The purpose of the present invention is to avoid the deficiencies of the above-mentioned prior art, and provide a simple, efficient and stable sequential power-on circuit in combination wi...
