Description
The TI Design TIDA-00289 proposes to integrate current control and plunger movement detection into the solenoid coil. 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.
Features
- PWM based current control optimizes power consumption for peak and hold time or according to fixed time settings
- 2 options for plunger movement detection: Back-EMF and Hall sensor based
- Automatic switchover from peak to hold current mode at the end of completion of plunger movement
- Activates alarm signal on detection of faulty plunger movement, under voltage or controller over temperature
- Complies with EN55011-Class A conducted emission limits
