A power-on control circuit and related device

Abstract

The embodiments of the present application disclose a power-on control circuit and a related device. The circuit includes: a power-on control unit and an anti-leakage circuit; a first port of the power-on control unit is connected to a power-on control pin of a chip, and a second port of the power-on control unit is connected to a power-on control pin of a chip. Grounding, the third port of the power-on control unit is connected to the first port of the anti-leakage circuit, the second port of the anti-leakage circuit is connected to the power supply, and the third port of the anti-leakage circuit is grounded; the power-on control unit is used to receive the power-on sent by the anti-leakage circuit After receiving the signal, the level of the power-on control pin is controlled to realize the function of the chip automatically turning on. By implementing the embodiments of the present application, through the power-on control unit and the anti-leakage circuit, the functions of the chip can be automatically turned on, off, and anti-leakage, and the circuit design is greatly simplified, and the circuit use efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, and 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 arranged in 5G mobile communications , so that the energy consumption of 5G network increases exponentially. Therefore, it has become a common method to reduce energy consumption to automatically start or shut down the equipment. [0003] At present, the general boot control method is to ground the boot control pin of the chip to achieve the purpose of automatically booting after power-on, or connect the boot control pin of the chip to the general transmission interface of the micro co...
