Part Number: BQ25616

When USB input, the maximum load is 1.2A (without battery). Can the load capacity be improved (such as load to 2a)？

Hi,

Is the 1.2A the USB max output current or the max SYS load current? Which "load capacity" current are you referring to?

Thanks,

Ning.

No battery：

1.When the load is set to 0.3A, then power up the USB, at which time the BQ25616 output voltage is normal.
2.When the load is set to 0.4A, then power up the USB, the BQ25616 output voltage is only 1.7V at this time.

Can I adjust the peripheral circuit? Is the output voltage normal when the load is large？

Hello,

Can you clarify further which load you are referencing? The charger can supply up to 1.2A with the OTG capability, what pins are you measuring during your test, is the 0.3A and 0.4A load on the VSYS?

What are your peripheral component settings?

Sincerely,

Wyatt Keller
