The invention discloses a power supply control circuit, and relates to the technical field of circuits. The power-on process of the power supply control circuit meets the requirement that the secondary power supply is turned on after the output of the primary power supply is stable, the secondary power supply is turned on through the indication of the signal of the indication pin used for representing the output state of the primary power supply, and the power supply control circuit is suitable for various types of primary power supplies; according to the process, the requirement that the secondary power supply completes the power-off process and then the primary power supply is turned off is met, and for secondary power supplies of other models, only the power supply of the last stage in the power-off time sequence needs to be selected as an output signal of the secondary circuit, so that the method is suitable for secondary power supplies of various models. Therefore, the power supply control circuit can be compatible with primary power supplies of different models and secondary power supplies of different models while meeting the time sequence control requirement, and the time sequence control chip does not need to be replaced for the primary power supplies of different models and the secondary power supplies of different models, so that the verification and time cost is reduced, and the time sequence control efficiency is improved. And the time sequence control efficiency is improved.

    本发明公开了一种电源控制电路,涉及电路技术领域。该电源控制电路的上电过程满足了一级电源输出稳定后,再开启二级电源的需求,通过用于表征一级电源的输出状态的指示引脚的信号的指示开启二级电源,适用于各种型号的一级电源;该过程实现了二级电源执行完下电流程,再关闭一级电源的需求,且对于其他型号的二级电源,只需选择下电时序中最后一级的电源作为二级电路的输出信号,故而适用于各种型号的二级电源。可见,该电源控制电路在满足时序控制需求的同时,可兼容不同型号的一级电源和不同型号的二级电源,且由于对不同型号的一级电源和不同型号的二级电源不需要来回更换时序控制芯片,故而,降低了验证和时间成本,提高了时序控制的效率。
