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
