I had an issue with my Energy Management modules with the power company service having short term power outages such as for a few seconds or minutes. I designed a circuit/PCB that uses blocking diodes from the input of a 5VDC power source using a wall wart that was powered by the local power company. My backup power is supplied by a 12VDC 7Ah battery with a DC step down BUCK converter reducing it to 5.1VDC and connected to a blocking diode. This setup eliminates the voltage from one source to come in contact with the other power source. The nice thing about using the blocking diodes is that it basically uses the source with the highest voltage input, which in my case is the 5VDC Wall Wart. When the Local power company's power is interrupted the power from the battery is used. Oh, the battery is charged by a small Solar panel and connected to a $8 USD tiny Solar Charge Controller. Has been working fine for the last 1.5 years. I do have 2 Super Capacitors, but I am not sure that I want to move to a setup using them as I am never sure as to how long the Power Company will interrupt service. The last time was for 6 hours so they could replace equipment at the sub-station. I will find something to use them on, but all my projects have UPS circuits that I made for them. Good Video!

Appreciate the comment and the information on your back power system. It would take a lot of super capacitors to match you 7Ah battery pack capacity so batteries sounds like the way to go for your backup power. Also you probably don't need the fast charging and high cycle count of super caps. You probably could stretch your battery power a little farther by replacing the blocking diode with a low on resistance MOSFET. What is the max power of your solar panel setup for charging the battery?

Impressive chip
Great project and walk-through. :-)

Awsome Thank you.
