Hi. I am jason.

I'm making the power block diagram of a circuit with BQ25890.

Actually, I'm not familiar some words in a datasheet of BQ25890.

One of the words is REGN.

I guess that REGN is among reference voltage to check status. Is it right?

Could you let me know the meaning of REGN?

Hi Jason,

REGN is connected to the output of a linear regulator, powered from VBUS. This voltage source is used to power the IC's internal circuitry and as a pullup for external resistors.

Please let me know if you have other questions.

Thank you.
Could you explain the word's meaning?
REG of REGN is a regulator. Then, what is N of REGN.
I hope your answer.
