I would like to have a converter that is able to variate the voltage within the device SAFELY.
Safety is a huge concern for me and I want to be able to tell people that my device is one of THE safest mods there is.
I would like to be able to use a single cell ( 3.7 V nominal voltage, 10-15 amp resistance, and can run from 4.2 being max charge and cut off at 3.0 V when discharge occurs ) to be able to power everything as well as one that is suitable for 2 cells ( both cells would be identical as stated for single cell except x2 batts) in a series/parallel. I would like to have the voltage to be regulated variably from 3.0 V - 7.0 V while having protection for thermal monitoring, amperage limiting to 3.5 amps, Battery monitoring/over-discharge protection and will cut off when the battery is discharged to protect it, reverse polarization that protects against reverse battery install, short circuit protection/ atomizer protection, and a 16 second shutoff if you forget to turn off the device and put it in something and pushes the button so it will cut off after the button is pressed for 16 secs.
I would like to incorporate a chip that resembles everything that I have stated above.
I can create wire schematics and come up with a way to run these chips but having only a Voltage-in and Voltage-out on a PCB with the converter and/or whatever else I needed would be ideal if you do that kind of thing.
Let me know if something like this would be feasible.
One of the reasons i want the all inclusive protection features is I am going to be using Li-Mn IMR cells which are 'Safe Chemistry' batteries but are UN-PROTECTED.
They are UN-protected but are the safest to use because of the chemistry and with a protection circuit via PCB with all the corresponding converter or MCUs then it would be a lot safer than using other lithium based batteries that aren't the safer chemistry.
