Part Number: BQ25175
Other Parts Discussed in Thread: BQ25170, BQ25180

Dear Sir/Ms.

I was discussing the charging IC solution with my customer today. My customer's product is a watch. Battery is 150mAh.
The BQ25175 is a good solution, but the output voltage is 4.35V. Do we have a version of BQ25175 that outputs 4.2V?

Best Regards,

Hi Kami,

How about the BQ25170? This device has an external VSET pin so you can set the battery regulation voltage as needed.

Do you need a WCSP package?

Hi Kami.

Then I would recommend BQ25180. We have samples and evm available. It is an I2C based device so you can adjust battery charge parameters.
