TPS25750: TPS25750 technical issues

Part Number: TPS25750
Other Parts Discussed in Thread: BQ25713, , BQ25731,

Hi Ti Team,

We also need to consider that the BQ25713 does not have a TS pin, the NTC of the Battery pack currently receives the ADC pin of the BT module, if the BT module detects that the temperature is too high, how to notify the BQ25713 to change the charge and discharge situation.

 

The definition of I2C needs to be confirmed with you.

<1> Does I2C require a second set from TPS25750 to BQ25713?  As if this makes sense, the BQ25713 is set to receive instructions after the TPS25750 shakes.

<2> All BT module's I2C as the master, connected to the slave end of TPS25750?

<3> From BT module's I2C as the master, connected to the TPS25750's master?

    Hi,

    May I know why you choose to use BQ25713? I would recommend using BQ25731 as this is also used on the TPS25750EVM and you can test out your configuration on the EVM.

    In general, TPS25750 talk to the BQ device through I2C3m and other I2C master device will talk to TPS25750 through I2C2s.

    Regards
