Solenoid drivers – Design & development
This design drives 8 seven-segment digits using a low-cost MSP430 and two DRV8860 octal low-side drivers. The display module gain benefits from DRV8860 on wide supply range, high current capability, PWM brightness control, serial daisy chain connection and expandable outputs for hundreds of LEDs.
This design includes dual DRV8860 and an MSP430 value line MCU to provide 16-channel low side driver for Relays, LEDs, and Unipolar steppers. An innovative energizing time and internal automatic PWM duty control provide obvious energy saving function especially for relay and solenoid driving.
