BQ27Z558: How to reduce power dissipation?

Paul Yeh

Part Number: BQ27Z558

Hi team,

My customer would like to reduce sleep mode power consumption and they are asking can they increase these resistor value? And what is the max resistance thay can use?

Please comment below three pink circle area.

Thanks

This won't appreciably reduce power consumption. Do not increase the 10Ohm resistor on BAT.

The 1k on BAT_SNS won't reduce power either. There is no external component that you can change that will noticeably reduce power consumption.
