if I use LTC3331 for piezo energy harvesting and if the dynamic force on the piezo material is zero , would there be any output ?
how do we model a piezo material in LTSpice, I tried in different methods using their equivalent circuits but couldn't have…
I AM TRYING TO HARVEST ENERGY FROM PIEZO ELECTRIC MATERIALS, WHERE I CAME ACROSS LTC3331.
I UNDERTAND THAT IT UTILISES THE BATTERY OR THE HARVESTED ENERGY ACCORDING TO THE AVAILABILITY.
IS AN EXTERNAL SUPPLY REQUIRED FOR POWERING THE IC ALONE.?
Is it possible for LTC3331 IC to charge the battery prior to providing a regulated output?
The input rectifier diodes internal to the LTC3331 have a 50mA limit. Additionally, there is a clamp that engages at ~19V with a 25mA limit; so, if your input voltage is >19V, you need to be limited to 25mA.
I'm not understanding what the…
Does the LTC3331 have an internal 50mA output current limit? or does the output need to be current limited externally?
Possibilities of LTC3331 VIN output null given a working piezo as harvester. DC source into VIN gives VOUT
Hi ZackThanks for your answer. I think that at the end I'll use a regulator connected to the battery to provide current to the higher load.In my project I have thought to use the LTC3331 to harvest energy by two indoor solar panels to provide power…
We certainly do. What kind of energy storage are you looking for? A supercapacitor or battery?
For now, I'll point you to LTC3331 which features supercapacitor storage as well as a rechargeable battery. Note that you should put…
There's no actual limit. That won't damage the IC, unlike the 50mA limit of AC1/AC2 or the 25mA limit of the clamp. Rather, the Ivin is a function of your input voltage/output voltage and how much current you pull.
