BQ25505EVM-218: Peltier module and charge

John73

Part Number: BQ25505EVM-218

Hi,

I'm quiet new on this kind of product. I read all of the user's guid but I have a question.

I want to test the energy collected by a Peltier module and transformed by the BQ25505. Can I put a use a resistance to replace the BAT_SEC and measure voltage on it or will it make a mess with the bq ? My Vin should be between 500mV and 1200mV.

Regards,

John

John,

Are you wanting to put the resistor on BAT_SEC to act as a load you might see from a system? If so, you are better off putting the load on VSTOR instead.

If you just want to measure the output of the charger, place at least a 100uF capacitor on BAT_SEC and measure the voltage on the cap.
