Hi Minki,

I think TPS65133 already has the input UVLO.

You can find this in datasheet "8.2 Functional Block Diagram".

But the voltage threshold is too low for Li-Ion battery,is there had any method make it lock on around 3~3.3V?

Thank You

Hi Minki,

I think the UVLO threshold can't be changed since this circuit is inside the IC.

Hi Minki,

Do you have more questions?

If not, I'll close this case later.
