Dears,

I want to power my in-door sensor with mini Solar panels，which is output 0.8~1.5V, and my Li-on battery is 3.7V.

Could you offer a device for boost charger? Thanks a lot.

I only need 1mA recharging current.

Hi Martin,

there should be charger for this kind of application. I change the post to charger forum.

Martin,

If you need boost charger, Please reference BQ25882.

This part can support vin=5V and 2cell battery charger.

Thanks

Hi Paul,

The input voltage needed is 0.8~1.5V, BQ25882 cannot match it. Could you offer lower input Charger? Thanks a lot.

Martin,

The closest device I think should be "BQ25504".

This part is our Ultra Low Power Boost Converter with Battery Management for Energy Harvester.

And only support 1cell battery.

Thanks
