DRV104

SBVS036B – SEPTEMBER 2003 – REVISED MARCH 2006

1.2A PWM High-Side Driver

for Solenoids, Coils, Valves, Heaters, and Lamps

DESCRIPTION

FEATURES

● HIGH OUTPUT DRIVE: 1.2A

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.

● WIDE SUPPLY RANGE: +8V to +32V

● COMPLETE FUNCTION:

PWM Output

Adjustable Internal Oscillator: 500Hz to 100kHz

Digitally Controlled Input

Adjustable Delay and Duty Cycle

Over-Current Indicator Flag

● FULLY PROTECTED:

Thermal Shutdown with Indicator Flag

Internal Current Limit

Separate supply pins for the circuit and driver transistor allow

the output to operate on a different supply than the rest of the

circuit.

● PACKAGE: HTSSOP-14 Surface-Mount PowerPAD™

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.

APPLICATIONS

● ELECTROMECHANICAL DRIVERS:

Solenoids, Valves, Positioners, Actuators, Relays,

Power Contactor Coils, Heaters, and Lamps

● FLUID AND GAS FLOW SYSTEMS

● FACTORY AUTOMATION

The DRV104 is specified for –40°C to +85°C at its case. The

exposed lead frame must be soldered to the circuit board.

● PART HANDLERS AND SORTERS

● PHOTOGRAPHIC PROCESSING

● ENVIRONMENTAL MONITORING AND HVAC

● THERMOELECTRIC COOLERS

● MOTOR SPEED CONTROLS
