[0002] At present, the laptop products are imported into manufacturing and other applications. Currently, these series of products involve multi-section and multi-string power management IC chips (such as BQ40Z50, BQ40Z651, etc.). Since the mechanism and communication timing waveform of the current power management application chip are still different from the standard I2C communication protocol. The current manufacturing industry uses the traditional EV2300 (third-party hardware module) for multi-channel communication reading for the power management IC of this laptop. The result of this method is high manufacturing cost and high resource occupation. The connection between EV2300 and the device computer is USB connection, which has high requirements for computer configuration.
