Problems solved by technology

Generally, most of the voltage sequence output control modules designed on the market are designed using chips such as microcontrollers and processors. However, because the cost of the control chip is relatively expensive and a programmer must write a corresponding program to control it, the voltage sequence output control module higher production costs

Abstract

A voltage sequence output circuit is used to output a starting voltage to a plurality of electronic devices orderly, and a first control circuit comprises a nor gate and a first electric switch. The input end of the nor gate is connected with the first and second input ends, and the output end is connected with the first end of the first electric switch. The second end of the first electric switch is connected with a voltage output circuit, and the third end is connected with a voltage source. The voltage output circuit comprises a second electric switch and a third electric switch. The first end of the second electric switch is connected with the first input end and is connected with the voltage source via a first resistor, the second end is connected with the second end of the first electric switch, and the third end is connected with a first output end and the second end of the third electric switch. The first end of the third electric switch is connected with the second input end and is connected with the voltage source via a second resistor, and the third end is connected with a second output end. The voltage sequence output circuit is composed of the electronic components of cheap prices, thereby reducing the production cost effectively.

Description

technical field [0001] The invention relates to a voltage sequence output circuit. Background technique [0002] With the improvement of living standards, more and more electronic devices are used, which makes it necessary to connect multiple electronic devices to one power interface, and electronic devices often consume a lot of power when they are powered on. If multiple electronic devices are turned on at the same time Will make the circuit is likely to be overwhelmed and burnt. [0003] The traditional solution is to adopt voltage sequential output control for multiple electronic devices, so that the electronic devices connected to the same power interface are turned on in time-sharing, so as to reduce the instantaneous load of the circuit at the same time. Generally, most of the voltage sequence output control modules designed on the market are designed using chips such as microcontrollers and processors. However, because the cost of the control chip is relatively expe...
