Tired of the loud noise from conventional fans and high power consumption of air conditioner indoor units? Are you searching for a stable, high-efficiency, low-noise motor drive solution?

Today we introduce our full lineup of 3-phase BLDC motor drive ICs, specially designed for ceiling fans, industrial fans and air conditioner indoor units. Covering sensorless control, Hall sensor-based solutions and 600V gate driver chips, our portfolio fully meets performance requirements across diverse applications!Images for reference only

Our solutions support the two mainstream control architectures: sensorless control and Hall sensor control. The product portfolio consists of three core series to match different motor control requirements, enabling efficient, quiet and reliable operation for your end products.

✅ Sensorless 3-Phase BLDC Controllers No extra Hall sensors required. This cuts BOM cost and simplifies motor structure, ideal for mass-produced ceiling fans and industrial fans.

✅ Hall-Based 3-Phase BLDC Controllers Paired with Hall sensors, these controllers deliver strong starting torque and stable low-speed performance, perfect for industrial applications demanding precise speed regulation.

PT2505: Sinusoidal drive solution with ultra-low noise and smooth torque output. It is well suited for air conditioner indoor units and industrial exhaust fans with strict quietness requirements.

✅ 600V Gate Driver ICs Provide robust drive and protection for high-voltage BLDC motors to improve system stability and safety, serving as the core building block for high-power industrial fans and air conditioner indoor units.

PT5606 / PT5607: General-purpose high-voltage gate drivers compatible with multiple topologies, supporting motors of various power ratings. PT5616/A: Cost-effective high-voltage driver with built-in multi-protection functions to reduce system failure rates.

Key Advantages of Our BLDC Drive Solutions

1. Reduced Noise, Eliminates the Humming of Traditional Motors Whether adopting FOC sinusoidal drive or optimized trapezoidal control, our solutions drastically cut motor operating noise. Ceiling fans run nearly silently, and air conditioner indoor units deliver soft airflow without disturbing rest at night.

2. High Efficiency & Energy Saving to Lower Long-Term Operating Costs BLDC motors are inherently more efficient than brushed motors. Paired with our optimized drive firmware, power utilization is further improved and power draw reduced. For industrial fans and air conditioner indoor units running continuously, this translates to substantial annual electricity savings.

3. High Stability & Reliability for Wide-Range Operation From low-power residential ceiling fans and heavy-duty industrial fans to frequently cycled air conditioner indoor units, our solutions offer consistent control and comprehensive protection. They extend motor service life and reduce after-sales maintenance expenses.

4. Flexible Selection to Fit Different Product Positioning We have matching drive options for cost-sensitive entry-level designs and premium products focused on low noise and energy efficiency. Accelerate your product upgrade and capture more market share.
