BQ76PL455A-Q1: BQ76PL455A-Q1

Part Number: BQ76PL455A-Q1

Hi, I have some question regarding BQ76P455A.

1) Data frame sent through UART to configure BQ is different in Example code and BQ software design reference manual why it is so? is there any method to formulate this frames?

2) Is there any way to ensure BQ is wake up properly and ready for communication?

3) Is it require to connect individual cell voltages to BQ IC in order to wake up IC and  start communication?

  • Hi Aniket,

    1) The details on the creation of the frame are provided in the datasheet in section 7.5.

    2) Section 7.4.5 of the datasheet provides information on calculating the timing required. Additionally the current consumption can be monitored. When the part enters idle mode the current consumption should be Iidle.

    3) No, individual cell voltages are not required in order to wakeup IC.

    Regards,

    Geoff
