Hey,

We would like to use the QCA4004 / SP144 on a custom board and would like to supply power from a battery / batteries (not pre-regulated 3.3v).

The only thing we found at the datasheet about the supply voltage is in section 1.7.3 saying:

"The QCA4004 has an integrated power management unit (PMU) that generates all the power supplies required by its internal circuitry either from an external battery or a 3.3 V supply"

Can someone please advice, what's the supported voltage range when using an external battery?

Thanks,

Nir

Dear Customer,

As per dataheet mentioned, the input power should be 3.0~3.6V.

If use battery, it's better to keep as 3.14~3.46.

 

Regards,

Ray
