higher power TEG MPPT charger

Other Parts Discussed in Thread: BQ25504

Hi,

I am working on an application for a MPPT Li-Ion single cell charger for a TEG with an output voltage of 0.5-2V and a power of up to 3W.

I would also like to charge the battery from an external source at 1A when required.

I like the look of the BQ25504 - but this application exceeds the power capabilities of this device.

Would you have any suggestions for a suitable device or combination of devices that might suit my application.

Thanks

Dave
