Low-power-consumption single-chip microcomputer type power supply management control system

Abstract

The invention relates to the field of single-chip microcomputer control, and particularly to a low-power-consumption single-chip microcomputer type power supply management control system. The low-power-consumption single-chip microcomputer type power supply management control system comprises a working part and a standby part. The working part is provided with a working power supply, a first DC / DC power supply conversion module, a single-chip microcomputer, a second DC / DC power supply conversion module, a peripheral device and a high-voltage module. The low-power-consumption single-chip microcomputer type power supply management control system has advantages of preventing standby power consumption of the power supply conversion module in the standby state of the single-chip microcomputer, greatly reducing integral power consumption of the system in the standby period, finishing a sleep waking-up task by means of a clock chip and improving system stability.

Description

technical field [0001] The invention relates to the field of single-chip microcomputer control, in particular to a low-power single-chip microcomputer power management control system. Background technique [0002] The low-power design of the electronic part of the traditional instrument focuses on the selection and software control of the single-chip microcomputer and peripheral devices. In the system with sleep and working state division, it relies on the sleep mode of the single-chip microcomputer to achieve low-power design, but in the sleep stage The power conversion unit and single-chip microcomputer still need to consume electric energy, especially when there is a large voltage difference between the power supply provided by the instrument and the voltage required by the single-chip microcomputer system and DC / DC conversion is used, the low power consumption design of the power management part is ignored, which limits the instrument. benefit of low power consumption. ...
