PWM Solenoid and Valve Driver using DRV103

• Solenoid and Valve Driver
• DRV103 IC

This tiny module is a PWM Solenoid and Valve driver using the Texas instrument’s DRV103 low-side DMOS power switch, employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors, and positioners. This board is also ideal for driving thermal devices such as heaters, coolers, lamps etc. PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, adjustable PWM allows fine control of the power delivered to the load. Output delay time and oscillator frequency are also externally adjustable.
