LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Analog Competency
Analog and Interface Product Attributes
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
variety of systems including: powertrain, chassis, comfort,
driver information, entertainment and safety. Microchip’s
broad portfolio of low-power analog products enable the
development of cost-effective solutions that address these
challenges and others facing the system designer.
Being one of the first companies to apply Non-Volatile
Memory (NVM) technology to the development process for
analog products, Microchip has utilized its NVM experience
to deliver innovative analog solutions with unchallenged
electrical characteristics.
Leveraging experience from the integration of analog
features on PIC®microcontrollers, nanoWatt technology
and low pin count packages, Microchip’s analog circuitry
consists of more than 400 different power management,
linear, mixed signal, thermal management and interface
products. As an innovative, market leading supplier of lowpower solutions, Microchip Technology continues to expand
its analog product portfolio to support the demanding needs
of the automotive designer.

LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
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.

LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
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.
Application Examples
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.

LOW POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Solutions for Connectivity Applications
Connectivity within the vehicle is dominated today by two
main network protocols: CAN (Controller Area Network) and
LIN (Local Interconnect Network). CAN utilizes a robust,
high-speed protocol, usually linking major nodes or
subsystems within the vehicle, such as ABS, airbag,
powertrain and suspension control modules. LIN is a lowspeed, single-wire network that usually links nodes within
a vehicle subsystem, such as body electronics, headlight
controls and occupant detection.
