a pulse-width modulated (PWM) output. Its rugged design is
optimized for driving electromechanical devices such as
valves, solenoids, relays, actuators, motors, and positioners.
The DRV103 is also ideal for driving thermal devices such
as heaters, coolers, 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. DC-to-PWM output delay time and
oscillator frequency are also externally adjustable. …
