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 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.
