The DRV102 is a high-side power switch employing a
pulse-width modulated (PWM) output. Its rugged de-
sign 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.
The DRV102 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 DRV102 is available in a 7-lead staggered TO-220
package and a 7-lead surface-mount DDPAK plastic
power package. It operates from –55°C to +125°C.
