The DRV101 is a low-side power switch employing a pulsewidth
modulated (PWM) output. Its rugged design is
optimized for driving electromechanical devices such as
valves, solenoids, relays, actuators, and positioners. The
DRV101 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.
The DRV101 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, analog
voltage, or digital-to-analog 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.
The DRV101 is available in 7-lead staggered TO-220
package and a 7-lead surface-mount DDPAK plastic power
package. It is specified over the extended industrial
temperature range, –40°C to +85°C.
