Abstract

The embodiment of the invention discloses a startup control circuit and a related device thereof. The circuit comprises a startup control unit and an anti-creeping circuit, a first port of the startup control unit is connected with a startup control pin of a chip, a second port of the startup control unit is grounded, a third port of the startup control unit is connected with a first port of the anti-creeping circuit, a second port of the anti-creeping circuit is connected with a power supply, and a third port of the anti-creeping circuit is grounded. The startup control unit is used for controlling the level of the startup control pin after receiving a power-on signal sent by the anti-creeping circuit so as to realize an automatic startup function of the chip, and the anti-creeping circuit is used for discharging in a first time period after receiving a conduction signal sent by the startup control unit so as to realize an anti-creeping function of the chip. According to the embodiment of the invention, through the startup control unit and the anti-creeping circuit, the automatic startup, shutdown and anti-creeping functions of the chip can be realized, the circuit design is greatly simplified, and the use efficiency of the circuit is improved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a power-on control circuit and related devices. Background technique [0002] With the development of digital control technology in the field of electronic circuits, more and more occasions require automatic startup or shutdown control of equipment, especially for communication equipment or circuits with high energy consumption, such as a large number of 5G base stations deployed in 5G mobile communications , so that the energy consumption of the 5G network increases exponentially. Therefore, automatic power-on or power-off control of equipment has become a common method for reducing energy consumption. [0003] At present, the commonly used boot control method is to ground the boot control pin of the chip to achieve the purpose of automatic boot after power-on, or to connect the boot control pin of the chip to the general transmission interface of the micr...
