Abstract

The invention relates to a power-on time sequence control circuit and system which are applied to the technical field of power electronics, and the power-on time sequence control circuit comprises a time sequence control module and a power-on management module. The power-on management module is connected with the time sequence control module; the time sequence control module is also connected with a to-be-adjusted pin of the functional module; the power-on management module is used for providing a power-on signal after power-on; and the time sequence control module is used for controlling the time sequence of the power-on signal, so that the signal input into the to-be-adjusted pin meets the power-on time sequence requirement of the to-be-adjusted pin, and the power-on time sequence requirement comprises power-on by delaying a preset time length. The problem that in the prior art, in the time sequence configuration modifying process, developers need to conduct adaptive configuration and develop corresponding codes, and consequently the time and capital investment cost is high is solved.

Description

technical field [0001] The present application relates to the technical field of power electronics, in particular to a power-on sequence control circuit and system. Background technique [0002] At present, with the increasing complexity of electronic and communication systems, electronic products are widely used. The realization of the functions of electronic products is often accomplished through different functional modules. In the working process of electronic products, it is necessary for the host to control the power-on, work, sleep, and shutdown of the functional modules. [0003] However, due to the differences in the design process, system, platform and manufacturer of the functional modules, the power-on sequence of the functional module products of different platforms is different, and the product iteration compatibility is poor. If you want to make the functional modules compatible, you often need to modify the timing configuration of the functional modules. ...
