Hi Expert,

Have a good day.

Could you help to explain what “12” in Equation (3) mean? It seems a voltage value?

And why this could be used to calculate OCP threshold?

Thanks!

Hi Leo,

This comes from an internal spec.

Hi Shiven,

Thanks for reply.

Sorry I am still confused.

This value is 1.22V, why in the equation is 12?

And how to understand the 12* RSET?

Best Wishes,

Leo Ma

Hi Leo,

1.22 has been rounded off to 1.2. While deriving the equation, it becomes 12.

This will help you understand the derivation.
