Imefungwa Kulipwa wakati wa kujifungua

Hi,

I have a source (TEG - Peltier Module) of a very small outup voltage 0.3-0.8 V.

My target project: I need a board to input the 0.3-0.8 Volts of my

source (TEG) in order to charge a small Li-on Battery. I dont care about the time it would take for the full charge. I have found an IC that I think would do the job. LTC3105. That is because in its application description it has the following:

- Solar Powered Battery/Supercapacitor Chargers

- Energy Harvesting

- Remote Industrial Sensors

- Low Power Wireless Transmitters

- Cell Phone, MP3, PMP and GPS Accessory Chargers

Firstly please let me know if this is possible and then we can discuss in further detail.

Hello. Yes, your idea is real, but the result is highly dependent on the temperature difference and the model of element. When a temperature difference of about 20 degrees output from element is comparable to the Zaidi

That is a good choice,LTC3105 I have used for ambient light energy harvesting for indoors, there are some trick but it can generate from the lowest and widest range of voltage.

I can provide you with full solution including schematics, BOM (layout and prototype per your request). But it would be possible if you can correctly formulate your requirement as for the Load. Just "Li-ion" cell does Zaidi

I think that LTC3105 is not a better choise for this task because it needs at least 225mV of input voltage. May be LTC3107 is better. It gives an opportunity to work at input voltage from 20 mV due to input transforme Zaidi

Hi! This sounds like an easy project. This should be done within one day, but in case there are some other specifications not yet known, I put up 3 days. I have been working with AVR technology for about 5 years Zaidi
