Current Controlled Driver for 230V AC Solenoids Reference Design


Design files


TIDA-00284 proposes to integrate current control and plunger movement detection into an AC solenoid coil. This reference design provides a solution to control the solenoid current using a PWM-based controller along with a Hall sensor to detect plunger movement and switch from peak current to hold current mode Various applications in the field of industrial automation and material processing will benefit from up-to 70% reduced power consumption, accelerated process time, greatly simplified usage and enhanced monitoring capabilities.

  • PWM based current control optimizes power consumption for peak and hold time or according to fixed time settings
  • Optional plunger movement detection based on Hall sensor
  • Automatic switchover from peak to hold current mode at the end of completion of plunger movement or pre-set timer
  • Activates alarm signal on detection of faulty plunger movement, under voltage or controller over temperature
  • Complies with EN55011-Class A conducted emission limits
