The DRV102 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 DRV102 is available in 7-lead staggered TO-220
package and a 7-lead surface-mount DDPAK plastic
power package. It operates from 鈥?5擄C to +125擄C.

DESCRIPTION
The DRV102 is a high-side power switch employing
a pulse-width modulated (PWM) output. Its rugged
design is optimized for driving electromechanical de-
vices such as valves, solenoids, relays, actuators, and
positioners. The DRV102 is also ideal for driving
thermal devices such as heaters and lamps. PWM
operation conserves power and reduces heat rise in the
device, resulting in higher reliability. In addition, ad-
justable PWM allows fine control of the power deliv-
ered to the load. Time from dc output to PWM output
is externally adjustable.
