The refrigerator application utilizes advanced sensorless FOC control strategy, suitable for applications with a single compressor variable speed control in household refrigerators, military air conditioning, commercial air conditioning, and automotive air conditioning.

The technical specifications are as follows:

• Working Voltage: 165Vac – 275Vac

• Rated Current: 1.27A RMS

• Power: 260W 

• Maximum No-load Power Consumption: 0.5W

• Speed Range: 1200RPM – 4500RPM

• Operating Environment: -20℃ – 85℃ 

Application Advantages of the N32G031/N32G435 Chips:

• Supports single, dual, and triple resistor sampling for sensorless FOC control.

• Zero-speed closed-loop startup with low-frequency torque compensation, resulting in low vibration.

• Rapid thermal restart, capable of restarting within a few seconds.

• Constant speed output under different loads at rated power.

• Comprehensive abnormal protection with complete protection strategies for overvoltage, undervoltage, software/hardware overcurrent, overpower, stall, and phase loss.

Recommended Models:

• N32G031 / N32G435
