pulse-width modulated (PWM) output. Its rugged de-
sign is optimized for driving electromechanical de-
vices 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, re-
sulting 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 exter-
nally adjustable.
The DRV101 can be set to provide a strong initial
closure, automatically switching to a 鈥渟oft鈥?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 shut-
down 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 indus-
trial temperature range, 鈥?0擄C to +85擄C.
