The DRV104 is a DMOS, high-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. It 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. Time from dc-to-PWM output and oscillator frequency are externally adjustable.

Separate supply pins for the circuit and driver transistor allow the output to operate on a different supply than the rest of the circuit.

The DRV104 can be set to provide a strong initial solenoid closure, automatically switching to a soft hold mode for power savings. The duty cycle can be controlled by a resistor, analog voltage, or a digital-to-analog (D/A) converter for versatility. The Status OK Flag pin indicates when thermal shutdown or over-current occurs.

The DRV104 is specified for –40°C to +85°C at its case. The exposed lead frame must be soldered to the circuit board.
