PWM Solenoid and Valve Driver using DRV103
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.
The DRV103 can be set to provide a strong initial closure, automatically switching to a “soft” hold mode for power savings. A resistor, analog voltage, or Digital-to-Analog(D/A) converter can control the duty cycle. An output OK flag indicates when thermal shutdown or over current occurs.
Features
- Supply 8V to 32V DC
- Load Capacity 1.5A
- Trigger Input Voltage 1.5V to 5V DC
- Thermal and Current Limit Shutdown
- On-Board Power LED
- PCB dimensions: 28.25 x 20.63 mm
Applications
- Solenoids
- Valves
- Heaters, Coolers
- Lamps
- Relays
- Power Contactor Coils
- Hydraulics and Pneumatics Systems
Note: PWM Duty Cycle, Output Delay, Frequency Adjust are adjustable from external resistors
- Oscillator Frequency range 500Hz to 100Khz, the default set to 5Khz, Frequency can be altered by changing R4 ( Refer to Datasheet for more details)
- Delay Output: Default delay set to approx. 100 ms, Delay can be adjusted by changing Capacitor C1
- Duty Cycle is adjustable 10% to 95% , the default set to 95% can be altered by changing R3 (Refer to Datasheet for more details)

where can i buy it?
How many pieces do you need?
2 units
Where can I buy this driver circuit. I need 200 pcs. Please contact me asap surojit@smato.in
Please check your email. Thanks
Do you sell these modules?
Yes, we can produce them for you. Check your email.
Please send me order information.
Do you not handle something similar but at least 2 amps?
Check here: https://www.electronics-lab.com/project/9v-to-60v-pwm-2-3a-solenoid-valve-driver-using-drv101/
I would like a price for 10 boards completely populated with a 1 second Peak and 50% duty cycle. Please advise! Thanks!
Please check your email for a quote.
Can we buy several of those modules from you guys?
Would like to purchase?
This will be in stock in about a week. Stay tuned, or subscribe to the list to get a notification. Product page: https://www.electronics-lab.com/product/pwm-solenoid-and-valve-driver-using-drv103/
Hello, when will you have this item in stock again? Ty
How many boards do you need? It will be in stock in a few days. Let me know.
hello all right, I have a proportional valve that is 24v and can be modulated from 100mA to 280 mA that your circuit serves?
Yes, this can go up to 1.5A and 32V load. You will have to modulate the input if you want to regulate output current.
Hi;
So, I understand that this driver board can control a proportional valve. I can control the Trigger Input Voltage from 1.5V to 5V DC. Will this driver board regulate the output current to the proportional valve ( 24V) so I can control the opening percentage of the valve?
Can you quote me 10 pcs. as well?
Thanks.
Great projects by the way.
Yes, right. PWM duty cycle can be adjusted using R3. In this board the R3 is fixed for 95% duty cycle. In case you need to control PWM then you have to add an external potentiometer in place of R3.
