TPS6594-Q1: I2C interface recovery solution

Part Number: TPS6594-Q1
Other Parts Discussed in Thread: TDA4VM

Hi BU team

in the TDA4VM PDN-0B reference design, tps65941213/1111 were used to provide power supply to TDA4VM. During the operation, Leo's I2C interface was latched by the system issue, does toggle Enable (pin 20) pin make I2C interface recover? if yes, what' the requirements on the toggling pulse? if not, what's your suggestion?

Thanks

    Hi Ted,

    I am not sure what the I2C issue you are seeing is, but toggling enable will reset the power of the system so I expect that to recover the interface.

    Here is the timing requirements from the datasheet.

    Thanks,
