Solar charging circuit of HTTC-AB01 explained

Hello,

I am interested in powering a sensor node from the sun energy.
Where I can find any detailed documentation regarding solar charger characteristics as well as supported rechargeable chemistry types so I could asses charging curves and operation conditions to decide panels voltage and required current.
This part is missing in the documentation and I’d like to learn what is the real circuitry behind charging block and see some characteristics to understand its capabilities.

Thank you for providing necessary documents.

AB01 uses TP4054 charging chip, you can check the related manual of TP4054.

@shaffer Thanks for posting it! I will go thought the documentation.
