DRV101FKTWT

IC, SOLENOID/VALVE DRVR 1CH 2.3A TO263-7.

The DRV101FKTWT 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 solenoid/valve driver 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, adjustable PWM allows fine control of the power delivered to the load. Time from DC output to PWM output is externally adjustable. It can be set to provide a strong initial closure, automatically switching to a soft hold mode for power savings. Duty cycle can be controlled by a resistor, analogue voltage or digital-to-analogue converter for versatility. A flag output indicates thermal shutdown and over/under current limit. A wide supply range allows use with a variety of actuators.
