Texas Instruments PW0014A | Demoboard TIDA-00284
Current Controlled Driver for 230V AC Solenoids Reference Design
Overview
| Topology | Other Topology |
| IC revision | E1 |
Description
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.
Features
- 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 plungermovement, under voltage or controller over temperature
- Complies with EN55011-Class A conducted emission limits
Typical applications
- General Purpose Drives - AC Inverter & VF Drives
- HVAC Valve and Actuator Control
- Major Appliances - Refrigerators & Freezers
- Major Appliances - Dish Washers
- Analog Input Module
