BQ25713B: difference with BQ25713?

Matthieu Imbert

Part Number: BQ25713B
Other Parts Discussed in Thread: BQ25713,

Hello,

What is the difference between BQ25713 and BQ25713B?

The latter only a silicon revision of the BQ25713?

On the product selection page for charger ICs, the abstract for bq25713B mentions "Solar MPPT", but no mention of it in the datasheet.

How can I get some insight on this feature if it's really implemented?

Please let me know.

Thanks.

Regards.
Matt.

Hi Matthieu,

The difference is the I2C address. Otherwise they are the same.

Hello Kedar,

Thank you for your answer.

As for the "Solar MPPT" feature, I suppose it simply is the ICO fearire, isn’t it?

Please let me know.

Regards.

Hi Matthieu,

It is more so the VINDPM feature. By setting the VINDPM threshold to solar panel MPP (refer to solar panel specification. Normally set to 80% of OCV), this input voltage regulation loop will regulate the charge current so as to maintain the VBUS voltage at the VINDPM set point (which corresponds to solar panel MPP).

ICO helps understand the true input current limit of your adapter. The algorithm automatically identify maximum input current limit of power source without entering VINDPM to avoid input source overload. You can refer to this app note for more information on ICO: www.ti.com/.../slva812c.pdf
