+9V to 60V PWM 2.3A Solenoid Valve Driver using DRV101
The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, an adjustable PWM potentiometer allows fine control of the power delivered to the load. Time from dc output to PWM output is externally adjustable. The DRV101 can be set to provide a strong initial closure, automatically switching to a soft hold mode for power savings. The duty cycle can be controlled by a potentiometer, analog voltage, or digital-to-analog converter for versatility. A flag output LED D2 indicates thermal shutdown and over/under current limit. A wide supply range allows use with a variety of actuators.

How can I purchase this device without the Valve or the trim pot. I want to employ the circuit board with a GM temperature sensor (resistor) which will then communicate a pwm signal to a electromagnetic valve in a Viscous clutch.
We can produce this board if order quantity is >25 pieces. If this interests you, please use the contact us form to get it touch.
Hello can i control this board with external PWM signal from my controler
and what i need to change that i will be able to use this on my 6v DC solenoid valve?
I am not sure I understand what you are trying to achieve. This board will produce a strong signal to fire the solenoid and then it will switch to soft PWM driving to retain the latch. There is no need for an external PWM signal, as this is produced from DRV101.
so i cant contorling how much to open solenoid valve. some time i want to have open 70% another time only 50% with out turning valve off
Right, you can’t control the valve opening, it’s just ON/OFF
ow okay i think that i control how much to be open with my arduino with out turning him off
how can i get voltage down to 6V because i have 6V dc valve in use right now
The minimum input voltage for this board is +9V, i am not sure if you can make it work with 6V solenoid.
Do not consider my previous question. I found the module DRV101 version (2.3 A) Can I connect the driver to the Arduino or works without a microprocessor?
Glad you found what you were looking for. This can work as standalone driver as it produce the necessary signal to drive the solenoid.
Hello,
I need a driver circuit with the following specifications
The following are driver circuit design requirements for generating a DC pulse
can you please suggest any driver circuit available with the above-mentioned parameters
