Other Parts Discussed in Thread: BQ25731, TPS25750, USB-PD-CHG-EVM-01,
Hi Team,
My customer considers designing a Power bank (battery) application with TPS25750 and BQ25731.
Regarding the following E2E thread, there is the following comment.
https://e2e.ti.com/support/interface-group/interface/f/interface-forum/994386/tps25750evm-how-does-bq25731-terminate-charging-when-the-external-battery-is-used/3691235#3691235
---------------------------------------------
The TPS25750EVM only supports on on board emulated battery. If you want to actually connect a board to an external battery, then you should use the USB-PD-CHG-EVM-01.
---------------------------------------------
According to the comment above, I understand BQ25731 shouldn't be controlled by TPS25750 but should be controlled by an external MCU for the application.
In other words, I2C line shouldn't be connected between TPS25750 and BQ25731.
Is my understanding correct?
Best Regards,
Yaita
