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.

Features
  • Backup energy up to 6 joules (J)
  • Inrush current protection with auto retry
  • Capacitor charging time less than 0.5s
  • Lower BOM Cost
  • Design guide provides detailed description and performance test data
