Abstract

According to a wireless communication module power supply control method provided by the invention, a joint control circuit is adopted, a processor only needs to control the joint control circuit, a 3.8 V power supply and a 1.8 V power supply are powered on and off in the circuit, and whether a manufacturer module carries 1.8 V power supply output or not is identified so as to determine whether the 1.8 V power supply supplies power to the manufacturer module internally or externally. Reliable power-on and reliable power-off of the circuit are guaranteed, the power-on and power-off time sequence of the circuit is controlled, processed IO resources are saved, and the power-on stability and the power-off thoroughness are greatly improved.

Description

technical field

[0001] The invention belongs to the field of wireless communication power supply, in particular to a control circuit and method for wireless communication module power supply. Background technique

[0002] The current development of wireless communication is changing with each passing day. Untrusted communication technology is fully used in the fields of edge computing, AI, and big data. With the gradual commercialization of 5G technology, the reliability and stability of wireless communication are very important. At present, 4G technology is very mature. The power supply of 4G wireless communication modules on the market is 3.8V (3.3V~4.3V), while the power level of the data interaction line is 1.8V. Weak 1.8V power output, only need to provide a 3.8V power supply to the module at this time, and the built-in 1.8V power supply cannot supply power to other circuits. Some modules do not have 1.8V power output, so two power supplies must be provided at this tim...
