The DRV102 is a high-side power switch employing apulse-width modulated (PWM) output. Its rugged de-sign is opTImized for driving electromechanical devicessuch as valves, solenoids, relays, actuators, andposiTIoners. The DRV102 is also ideal for drivingthermal devices such as heaters and lamps. PWMoperaTIon conserves power and reduces heat rise inthe device, resulTIng in higher reliability. In addition,adjustable PWM allows fine control of the powerdelivered to the load. Time from dc output to PWMoutput is externally adjustable.The DRV102 can be set to provide a strong initialclosure, automatically switching to a soft hold mode forpower savings. Duty cycle can be controlled by aresistor, analog voltage, or digital-to-analog converterfor versatility. A flag output indicates thermal shutdownand over/under current limit. A wide supply rangeallows use with a variety of actuators.The DRV102 is available in a 7-lead staggered TO-220package and a 7-lead surface-mount DDPAK plasticpower package. It operates from –55°C to +125°C.
