Automotive Capabilities
HVAC Control
In-vehicle heating, ventilation and air conditioning (HVAC) systems are
designed to provide passengers with a comfortable environment by
controlling various motors, flaps and actuators. Networked sensors
throughout vehicle provide inputs for control of solenoids and motors of
various types (i.e. brushed, BLDC, steppers, etc).
Typical Applications
■ Fans
■ Blowers
■ Pumps
