BQ25710: Regarding battery charger BQ25710 SMbus compatibility with standard I2C bus

Hi,

No, the BQ25710 is a SMBus and should not be used with I2C. If a similar I2C part is needed, I would recommend one of the following:


For example, the BQ25713.

Thanks,

Hi,

You should be able to get them through your local TI sales contact. I am not too familiar with the sales process, but I would suggest trying the following link.

https://www.ti.com/info/contact-us.html 

As for evaluation or prototyping, we do have the evaluation module available.

The major differences are listed in the image attached.



The input current and charge current control registers for both parts are capable of the same max level. You can get some more information on the datasheets of the respective parts.

Thanks and hope this helps,

Hi,

Please use SMBus for SMBus parts. SMBus and I2C are similar but they are not the same interface. Depending on what the processor is (simple single chip, running OS, etc.), there could be unexpected problems in production. Some of the differences are also stated clearly on the link you attached.

For example, if you use the SMBus port of EV2400 (that we recommend to people to evaluate our chargers) on some of our I2C based chargers, there is a good chance you can't communicate with it. And the same applies if you do the opposite (EV2400 I2C port on SMBus).

Our SMBus parts will adhere to the SMBus specification and our I2C parts will adhere to the I2C specification. 

Thanks and hope this helps,

Peng
