LP8868Z-Q1: Ruvp1 and Ruvp2

?? ?

Part Number: LP8868Z-Q1

Tool/software:

What are the requirements for Ruvp1 and Ruvp2？Can I use Ruvp1=200Kohm and Ruvp2=1Mohm？

If the internal LDO drives the UVP pin, the Ruvp2=1Mohm resistance is selected, 5V/1MΩ=5uA>1uA is satisfied leakage current requirement.

Hi,

Depending on the 1uA inject current and the voltage on UVP is 1.2V.

Consider the resistor value, the voltage threshold on Ruvp1 is 1.4V.

Pls consider the VIN, Vf and resistor margin in read case.
