Hi, I'm a student working on a university robotics project and I need help choosing some electronically-controlled switches.
The basic idea:
I have two capacitors, and I’m using them as temporary batteries.
My approach:
To achieve the voltage and current levels I require for my load, I’ve run PSpice simulations and come up with a switched-capacitor scheme where I charge one capacitor, then disconnect it and charge the other capacitor, then connect them in series to power the load. (See below for my schematic, voltage and current simulations.) These switches will be controlled by signals from my microcontroller. Nothing except my load will be powered by these capacitors.
My problem:
Given the simulation data, I know I need switches capable of handling up to 6V and 70mA; I’m having trouble finding an IC or something that will work for me.
Alternate:
My advisor suggested I look at relays instead of switches, but I’d prefer some kind of IC considering my size constraints.
Any and all advice is welcome! Thanks!
