BQ24773: BQ24773

Part Number: BQ24773
Other Parts Discussed in Thread: BQ24770,

Hello

Previously, I worked with BQ24770 and now I need to work with BQ24773.

I identified only one difference between them. The BQ24773 needs 1.8V connected via a 10K resistor on the SDA and SCL pins, while the BQ24770 needs 3.3V.

Could I keep 3.3V on the BQ24773 too?

Another point, the PROCHOT Pin is also connected with the 10K resistor at 3.3V, could I connect the PROCHOT Pin at 1.8V?

 I would like to use only one voltage regulator , 1.8V or 3.3V.

Thank you

    Hi Pedro,

    Yes, you can use the same 3.3 V pull-up rail for both the BQ24770 and the BQ24773.

    The differences between the two chargers are summarized in the table below:

    Best regards,
