Description

TIDA-00500 is a reference design to provide power to load for short duration of time after a power interrupt has occurred. Traditionally Programmable Logic Controllers (PLCs) are equipped with a recharge battery source for alternative power. This battery source often suffers from drawbacks like complex charging topologies: charging time: periodic maintenance: and eco-hazards. In scenarios where PLCs need to be functional for a short duration of time after power interrupt: a capacitor based backup is a much simpler and more effective approach because of the higher power density in comparison to a standard battery-based solution.
