Tool/software:

Hi team,

I'm looking for a standalone device with charging current of 5 ~ 10mA ( for 1cell Li-ion).
*Vin : 5V(USB power)
BQ25180 is close to the SPEC, but it is I2C controlled.
Do you have any ideas?

Hello Kengo,

The BQ25170 is a great option for your requirements. It's a standalone linear charger designed for single-cell Li-Ion batteries and operates from a 5V USB input supply.

I also recommend checking out the TI battery charger parametric part search page, where you can filter through our catalog of chargers:
