PowerPAD is a trademark of Texas Instruments.
The DRV103 is a low-side DMOS power switch employing
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.
The DRV103 can be set to provide a strong initial closure,
automatically switching to a “soft” hold mode for power
savings. A resistor, analog voltage, or Digital-to-Analog
(D/A) converter can control the duty cycle. An output OK flag
indicates when thermal shutdown or over current occurs.
Two packages provide a choice of output current:
1.5A (SO-8) or 3A (PowerPAD™ SO-8 with exposed metal
heat sink).
The DRV103 is specified for –40°C to +85°C.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may de-
grade device reliability. (2) See Bypassing section for discussion about
operating near maximum supply voltage. (3) Higher voltage may be applied
if current is limited to 2mA. (4) The Status OK Flag will internally current limit
at about 10mA.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
