Abstract

The invention discloses a multi-chip integrated circuit and an interactive communication method thereof. A plurality of low-voltage chips are connected in series to replace an ultra-high-voltage chip, so as to reduce the requirements for chip technology, and a plurality of chips are connected through internal dedicated communication ports. For communication, the reliability of communication is enhanced by using differential transmission. The end-to-end connection of two adjacent chips and the arrangement of the low-voltage power supply make the pressure difference between the communication ports between the two adjacent chips smaller.

Description

technical field [0001] The present invention relates to a power electronic technology, and more particularly, to a multi-chip integrated circuit applied in a power supply and an interactive communication method thereof. Background technique [0002] like figure 1 Shown is the structural block diagram of a battery management circuit in the prior art. The chip IC is used to monitor the voltage of M cells. If the voltage of each cell is calculated at a maximum of 6V, the withstand voltage of port VC(n) will reach (6* M)V. In the application of multiple strings of batteries such as automobiles, the highest port VC(n) may reach more than 100V. This application has extremely high requirements on the process of the chip IC, and significantly increases the cost. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a multi-chip integrated circuit and an interactive communication method thereof, so as to reduce the requirements for the chip IC process,...
