WIPO Patent Application WO/2023/123900
Kind Code:
A1
Abstract:
Disclosed are a power-up time sequence control circuit and a system, which are applicable in the field of power electronics technology. The power-up time sequence control circuit comprises: a time sequence control module and a power-up management module; the power-up management module is connected to the time sequence control module; the time sequence control module is further connected with a to-be-adjusted pin of a functional module; the power-up management module is configured to provide a power-up signal after power-up; and the time sequence control module is configured to control a time sequence of the power-up signal, so that a signal input into the to-be-adjusted pin satisfies a power-up time sequence requirement of the to-be-adjusted pin, the power-up time sequence requirement comprising delayed power-up of a preset duration.
