The electrically controlled elements are the blower fan motor and flap valves that divert the airflow.
The blower fan motor is usually a simple brushed DC motor, with its speed controlled by a MOSFET operating in PWM or linear mode. The flap valves are usually controlled by an integrated IC.
Key MOSFET Requirements:
- Switching capability for PWM control
- Low package thermal resistance
- Low on-resistance
- Good current handling
LFPAK56 is well suited to HVAC applications due to excellent current handling and thermal performance.
Main benefits:
- Robust product using advanced copper clip technology
- Excellent current handling
- Low on-resistance
I2PAK & TO-220 are ideal solutions for HVAC systems where through-hole mounting is used to optimise thermal performance and current handling.
Main benefits:
- Separate current and thermal paths
- CVlamp, screw and solder mounting
- Low on-resistance
- High current handling capability
BUK7610-55AL is specifically designed for thermally stable linear mode control applications.
