Integrated MCU AFE battery management system scheme
NMOS: MSxxNxxSeries
PMOS: MSxxPxxSeries
16-string, CAN or RS485 communication BMS architecture 32-string, CAN or RS485 communication BMS architecture 32-string, CAN or RS485 communication BMS architecture
AFE integrates MCU inside, and PACK can complete power calculation and CAN transceiver protocol without setting MCU inside,
simplifying PCB design and reducing the number of peripheral components.
AFE communicate with each other through Daisy chains, and there is no need to isolate communication IC between AFE.
