Hello Yishan,

What do you mean by normal condition? Do you know what the input/output voltage and load is?

Hi Ethan,

The normal condition I mentioned here is corresponding to the quiescent working mode.

Because customer want to know the typical power consumption of BQ25758. I quickly checked the datasheet and can't found relevant parameter.

Input voltage:48V, Output voltage: 36V Output current:5A

Thank you

Hi Ethan，

It would be enough if you can give me a rough number or a typical number：）

Thank you，

Hello Yishan,

The quiescent current with EN_HIZ=0 with VAC=48V and VBAT=48V is around 433µA from VAC. With EN_HIZ=0, VAC=0V and VBAT=48V, the IBAT current is around 25µA
