DESCRIPTION
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 a 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 of –40°C to +85°C.
