Surface-Mount DDPAK 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. …
