temperature and air flow rate based on a preset temperature.
The following figure shows the block diagram of a typical HVAC system. Switching the power source from the gas engine
in conventional vehicles to the electric motor in HEVs and EVs results in a much quieter cabin, which can make the blower
noise from the AC or seat heating/cooling fan motor's noise particularly noticeable. Therefore, to minimize this noise and
improve thermal efficiency, it is customary to replace the conventional brushed DC motors used for blower and fan motors
with brushless motors.

Automotive exterior lamps, can be broadly classified into head and rear lamps. These lamps are increasingly transitioning to the B
use of LEDs, which feature lower power consumption and longer life besides providing a greater design flexibility.
One of the biggest drawback of LEDs, is that they generate a relatively large amount of heat, and therefore
require cooling, sometimes using fans, particularly for the high and low beam lamps (see block diagram below).
Fan speed is adjusted based on the amount of heat generated by the LEDs.
Many newer vehicles also integrate a self-leveling headlight function that determines if
the car is tilted forward or back and adjusts the headlights accordingly to ensure they
are pointed at road at all times no matter the position of the car in order to prevent
blinding oncoming drivers. This functionality is called levelling. ROHM offers a wide
range of dedicated LED drivers optimized for automotive LED applications.

With an emphasis on reducing emissions and increasing fuel economy, there is a race on increasing the engine efficiency .
The purpose of the engine control unit is to sense the status of the engine and the surrounding systems and control the
engine, especially the ignition.
Sensor and driver accuracy play a large role in engine efficiency. This applies to power supplies as well. ROHM offers a
wide lineup of power supplies that contribute to greater energy savings, miniaturization, and performance in ECUs of all
types. ROHM has also developed a broad portfolio of automotive-grade discrete products, including IGBTs for ignition
control.

Head-Up Display (HUD) systems in cars are normally mounted on or near the windshield to present useful information to
driver. This technology, first introduced in fighter planes, is getting adopted in the automotive industry for improving the
safety by enabling drivers to view relevant data, such as time, vehicle speed, and navigation information, without having to
take their eyes off the road. The block diagram below shows a sample HUD solution, in which the relevant information is
