® DRV 101 DRV101 DRV 101 PWM SOLENOID/VALVE DRIVER FEATURES q HIGH OUTPUT DRIVE: 2.3A q WIDE SUPPLY RANGE: +9V to +60V q COMPLETE FUNCTION PWM Output Internal 24kHz Oscillator Digital Control Input Adjustable Delay and Duty Cycle Over/Under Current Indicator q FULLY PROTECTED Thermal Shutdown with Indicator Internal Current Limit q PACKAGES: 7-Lead TO-220 and 7-Lead Surface-Mount DDPAK 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 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, –40°C to +85°C.

(2) Logic High enables output (normal operation). (3) Constant dc output to PWM (pulse-width modulated) time. (4) Maximum delay is determined by an external capacitor. Pulling the Delay Adjust Pin low corresponds to an infinite (continuous) delay. (5) Connecting the Delay Adjust pin to +5V reduces delay time to 3µs. (6) VIN at pin 3 to percent of duty cycle at pin 6. (7) A fault results from over-temperature, over-current, or under-current conditions.
