Abstract

The embodiment of the invention discloses a main power supply module and a power management system. The power management system comprises the main power supply module and at least two power receiving modules; the main power supply module alternately charges at least two power receiving modules in a working period through a first node, and any one of at least two power receiving modules does not perform charging and communication at the same time. The power supply management system does not need to use a bidirectional blocking switch tube, and the control scheme is simple and easy to realize.

Description

technical field [0001] The invention relates to the field of power electronics, and more specifically, to a main power supply module and a power management system. Background technique [0002] With the further requirements of consumers for earphone functions, the types of earphones are increasingly updated. The introduction and use of new earphones, especially the widespread use of TWS (True wireless stereo) earphones, put forward higher requirements for the power management system of earphones. Not only the charging box of the earphones needs to be able to charge the batteries in the left and right earphones through POGO pins, but also the charging box of the earphones and the left and right earphones are required to be able to communicate via UART through POGO pins. At the same time, the structure of the power stage circuit in the battery box is very important, which affects the communication between the charging box and the left and right earphones and the working method...
