Problems solved by technology

Disadvantages of this principle: 1. The power supply does not have anti-reverse function. If the input voltage is too large or the positive and negative poles of the power supply are reversed, the CPU will be burned directly; 2. The power supply only controls the power supply of the CPU, and does not Other peripheral power supplies are used for control, and other peripheral circuits still consume current
If low power consumption is required on some devices, the effect of low power consumption control is not ideal

Abstract

The invention provides a multifunctional controllable power supply circuit with functions of switching, reverse prevention, consumption reduction and detection. According to the invention, a power supply circuit is improved, so that the circuit not only has the function of providing voltage, but also has the functions of preventing reverse connection of a power supply, controlling power supply ofa peripheral circuit to reduce the power consumption of the whole machine and detecting the on-off state, so that normal use of each electrical component can be effectively ensured, and the ultra-lowpower consumption function can effectively prolong the service life of battery power supply equipment.

Description

technical field [0001] The invention belongs to the technical field of power supply circuits, in particular to a multifunctional controllable power supply circuit with switch, anti-reverse, consumption reduction and detection. Background technique [0002] Existing power circuits for powering the CPU, such as figure 2 shown. Its working principle is: when it is necessary to supply power to the CPU, press the switch S1, the transistor Q5 is turned on, and the power supplies power to the CPU. When it is necessary to control the power off of the CPU, press the switch S1, when the CPU recognizes the switch state, it outputs a low level, and the transistor Q6 is turned off, so that the transistor Q5 is turned off, and the CPU is powered off. Disadvantages of this principle: 1. The power supply does not have anti-reverse function. If the input voltage is too large or the positive and negative poles of the power supply are reversed, the CPU will be burned directly; 2. The power s...
