A multi-power supply management device for electronic products

Abstract

The invention discloses an electronic product multi-power supply management device, which comprises an IPMC module and a CHMC module, and is characterized in that the IPMC module and the CHMC module are connected with an I2C bus, wherein the CHMC module comprises a power supply management module, and the IPMC module comprises a plurality of power supply management modules; each power supply management module comprises a microcontroller connected with the I2C bus, a temperature monitoring point connected with the microcontroller, a power supply time sequence controller connected with the I2C bus and a power supply management unit connected with the power supply time sequence controller; the CHMC module controls the power-on / off time sequence of the IPMC module through the I2C bus; the IPMC module controls the power-on / off time sequence of multiple functional modules; and the functional modules of the IPMC module are set corresponding to the power supply management modules thereof. The electronic product multi-power supply management device solves problems of abnormal states and transient current limit exceeding of electronic products under an undervoltage condition.

Description

Technical field [0001] The invention belongs to the technical field of electronic product power management and relates to a multi-power supply management device for electronic products. Background technique [0002] With the development of digital circuit technology, under complex functional requirements, electronic products tend to be based on high-performance DSP and FPGA-based signal processing platforms or multi-core processing architectures, including high-speed large-capacity storage and high-speed communications, which makes electronic products say goodbye With a single 5V voltage, we have entered the era of low voltage and multiple power supplies. There are many types of power supplies, high system power consumption, under-voltage or transient current exceeding the limit will cause the system to work abnormally, so it is urgent to manage multi-power supply. Summary of the invention [0003] The invention provides a multi-power supply management device for electronic produ...
