BQ25756E: Register difference from BQ25756

Hi Ethan,

Thank you.

Since the maximum voltage is different between BQ25756 and BQ25756E, for example, the range of VAC_DPM is also different.
25756 D/S has detailed descriptions of each register, but it seems to be omitted in the 25756E D/S. Is there a detailed register map for the 25756E?

Best regards,
Goto

Hello Goto,

The VAC_DPM register is in the BQ25756E datasheet. Are you referring to a different register?

Hi Ethan,

Sorry I mistook, VAC_DPM is not appropriate example.

Regarding to REG0x1A, BQ25756E datasheet has lack of description about 6:5 .

Are there any other lack or omissions that I should be aware of when looking at the full 25756E register map?

Hello Shuhei,

Thanks for the clarification. Perturb and Observe wasn't working well for the BQ2575X family. We took out P&O from the BQ25756E datasheet.

We now have an app note for how to implement P&O externally: www.ti.com/.../sluab21.pdf

Let me know if this answers your questions.

Hi Ethan,

In other words, P&O does not work well on the 25756E, so it is omitted from the register map in the datasheet, and there are no other missing information, right?

Thank you very much,
