An Italian HVAC equipment manufacturer was developing a new series of energy-efficient commercial ventilation systems.
The design goal was to replace traditional AC motors with sensorless BLDC motors to reduce power consumption, noise, and maintenance costs.
The customer required a compact motor control IC capable of stable startup, smooth speed regulation, and reliable operation under continuous working conditions.
After technical comparison, JY02A (SSOP-20) was selected as the core BLDC motor control solution.
