BQ76PL455A: Detail Daisy-Chain Protocol of BQ76PL455A

Part Number: BQ76PL455A

We need use MCU to communicate BQ76PL455A  by Daisy Chain interface.

Can TI provide the whole Daisy Chain protocol?

    Hi Zhiang,

    The daisy chain protocol is proprietary, but is described in the datasheet along with the UART communication expectations. However, there is no need to have the knowledge of the protocol details for MCU communication. All that is needed for that is a single UART interface to communicate to the bottom-most device in the stack. If the device is properly addressed, then communicating to stacked devices is a matter of changing the address byte of communication and expecting slightly longer response packets for broadcast reads.
