Description

The TIDA-00998 TI Design shows multiple architectures for extending primary battery life using a secondary battery or supercapacitor with energy harvested from a current transformer (CT) or solar cells. Optimal Power management is done using efficient LED Drivers to drive series or parallel strings of LEDs to control intensity for uniform 360° visibility.

Features
  • Solar energy harvesting to charge li-ion battery, autoswitching between primary and secondary battery to power LED driver and fault indicator AFE
  • Interface to CT based load current harvesting subsystem to charge supercapacitor; PowerMux to autoswitch between supercapacitor and primary battery
  • Drives up to six independent LEDs and three channels paralled to drive high current LED using LP55231
  • Drives series connected LED strings using LM3509
  • Three level intensity control based on ambient light sensed using OPT3001
