LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Analog Competency
The demand for automobile electronics has never been
greater. Do you need lower quiescent currents? Does
your design require reduced board space? Designers
of electronic control modules within the automobile are
being challenged to deliver increased performance in a

Solutions for Low-Frequency Communications
Applications
Low-frequency communication systems provide
many benefits in and around the vehicle. In sensing
applications, it allows for the distribution of remote
sensors while eliminating the concern for wired
connection between the sensor and control module. In
other applications, a transponder becomes a mobile
device that can remain with the driver, or is attached to
another apparatus that can be transferred to/from the
vehicle when needed.

Solutions for Power Supply Applications
The growing deployment of navigation, entertainment and
communication equipment in modern cars, as well as the
utilization of most advanced semiconductor technologies,
has been changing the needs for voltage regulation in
the car. Automotive power supplies are used for DC-DC
conversion, DC voltage monitoring, pulse-width modulation
and digital control. Electronic Control Units are using

Automotive Applications Design Guide 7
A typical LED solution can be as simple as a battery and
a resistor, but with more complex dimming, flashing and
multi-color applications; and more rigorous requirements
in terms of matching brightness and color, there is an
increasing need to control and monitor the current in an
LED application.
Solutions for LED Applications
Traditional incandescent lamps are increasingly being
replaced by Light Emitting Diodes (LEDs). LEDs offer
compelling advantages, including a high level of light
efficiency, reliability, mechanical stability and long
operating lifetime. Because LEDs must be operated at
constant current, DC-DC converters with the capability of
efficiently translating the operating voltage into the LED
forward voltage are required. Further key elements of LED
control circuits are overcurrent protection, over heating
protection (temperature sensing) and efficient energy
utilization.

The number of sensors in
automotive applications
is rapidly increasing. Of
all sensing technologies,
temperature sensing is the most common. Knowing and
using the actual or relative temperature is critical. For
instance, other sensors such as pressure, force, flow, level
and position many times require temperature monitoring in
order to ensure accuracy.
