Hello,

I do not seem to have access to the datasheet, but it depends on how much charge current you want, what the charge voltage is, and what features you want.

Hi Michael,
Thank you for your reply.

I'm considering the following conditions.
Input Voltage: 5V
Charge Voltage: 4.2V
Charge Current: 1A ～ 2A
Feature: Support USB 2.0

Is it possible to meet these requirements with BQ25616?

Even if 1S4P is a single package, I think it depends on the performance (Impedance Balance) of the battery package whether the charging current is evenly divided into four.

Best regards,
