Heating Ventilation and Air Conditioning (HVAC)

[#1]

Overview

Heating, ventilation, and air conditioning (HVAC) systems are based on inputs from a variety of sensors, controlling different types of motors such as stepper motors for flaps and DC/BLDC blower fan motors.

NXP broad portfolio of 32-bit, 16-bit S12, and 8-bit S08 families of microcontrollers enables designers to meet the needs of a variety of HVAC applications. System basis chips (SBCs) combine physical network connection with power management. Intelligent eXtreme switches complete the system solution for DC motor blowers. BLDC motor control requires more complex algorithms. NXP’s MagniV products combine MCU with SBC functionality, network connection, and motor control, specific drivers, into a single package, providing a cost-effective small footprint system solution.
