BQ76PL536A fault signals without uC

Other Parts Discussed in Thread: BQ76PL536A, BQ34Z100

Hi team,

 

How much functionality does the BQ76PL536A lose with the absence of a uC in the system? More specifically, how are the error flags (FAULT signals, etc) read out without a host? How is the EPROM programmed/read?

 

(The system is the BQ76PL536A + BQ34Z100). Here, the PL536A is more like an AFE without a controller.

 

Thanks for the help,

Yvette

    There are two ways to detect fault.

    1. You must have FAULT_H pin connect toe 34Z100.

    2. Z100 must have SPI communitcation.

     

    Bottom line, PL536 is host mode. you must have uC with PL536. 

    You can't read out without host.

    Hi Roger,

    Thanks for the reply. Just to clarify:

    -The z100 + p536 set up requires a microcontroller for reading out fault signals.

    -For this set up: the pl536's FAULT_H pin is connected to the z100. Then the z100 communicates with the microcontroller through SPI? The z100's data sheet mentions nothing of SPI communication. I did see I2C mentioned.

    Is this correct? Thanks.

    Currently, Z100 can't communicate with PL536. As you mentioned above, PL536 is SPI communication which Z100 doesn't support.

    As of today, Z100 can't work with PL536.

    We don't have Z100+PL536 solution.

    We have Z100 solution with PL9XX.
