Abstract

The invention relates to a power switch sequential switch. The circuit comprises a power supply module, a master control chip CPU module and a voltage-dividing regulating module. The power switch sequential circuit has the advantages that time sequence requirements between power switches can be satisfied fundamentally, and a new solution is provided for regulating the time sequence problem of a power supply; a good and convenient time sequence solution is provided for different circuits, the solution can be shared by complex CPU chips, and wide application range is achieved.

Description

technical field [0001] The present invention relates to the technical field of power switches, in particular to the technical field of timing response, in particular to a power switching sequential circuit. Background technique [0002] For terminal communication equipment, it often includes multiple functions. For example, a PON network communication product often includes functions such as PON, WiFi, and voice. The timing problem of the power supply, and how to deal with the timing problem between the power supplies, usually adds an RC circuit to the power enable pin (such as figure 1 , 2 Shown), through the relationship of the RC circuit to change the requirements of different power supply chips on the power sequence. However, in some specific occasions, this design often does not have obvious requirements on the timing sequence of the power supply, so a better method is needed to solve the problem that the timing sequence requirement on the power supply is not obvious....
