PHOTOGRAPHIC PROCESSING
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 shutdown 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 pack-
age 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 devices 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, adjustable PWM allows fine control of the
power delivered to the load. Time from dc output to PWM
output is externally adjustable.
