Part Number: BQ35100

Hi Support,

In our application operation power for whole system is about (30mA~120mA), standby power is about 0.1mA.

Is it ok for bq35100? Can it can sense 0.1mA on 0.1 ohm resistor?

Thanks.

No, we do not have anything in our portfolio for 100 mOhm sense resistor. The noise level is too amplified.

Hi Kang Kang,

Referencing to the EVM design, please help to review below schematic.

Some points are still not clear for us since we will single battery at 3.6V.

REGIN should be connected to +VB in our case?
R1 NTC can use SMT part (p/n: NCP03XH103E05RL)? Due to limited PCB size we want to use SMT part.

Thanks.
