DC motor drive

BLDC is a brushless DC motor (Brushless Direct Current Motor), which overcomes the congenital defects of brushed DC motor and replaces the mechanical commutator with electronic commutator. Therefore, brushless DC motor not only has the characteristics of good speed regulation performance of DC motor, but also has the advantages of simple structure, no commutation spark, reliable operation and easy maintenance. The essence of the brushless DC motor is a three-phase AC permanent magnet synchronous motor that uses an electronic inverter to convert DC power into AC power and has rotor position feedback.
MOSFETs are widely used in motor drive fields such as: electric tools, fans, electric bicycles, garden tools, vacuum cleaners, electric fans and other related applications, and has the following advantages:
Provide better RDS(ON) and EAS to effectively reduce system temperature rise and improve impact resistance
• The product has good high-frequency switching characteristics, to achieve high efficiency, effectively reduce the system temperature rise, improve the reliability of the system
Withstand voltage 30~150V, SGT MOSFETs with lower internal resistance of 0.55mΩ (JMSL030SAG) and 0.57mΩ (JMSL040SAG), FOM as low as 47; Trench MOSFET with better impact resistance and JMTG035N04A
Package types include PDFN3x3/5x6-8L, DFN2020-6L, TO-220/247/251/252/263-3L, SOP-8L, SOT-23, SOT-23-3/6L, etc.
• Good consistency of product parameters and high reliability
• Complete product range to meet the needs of various motor drives for different application spaces and specifications
According to different voltage ranges, 30V-100V Trench & SGT MOSFETs are provided, which are suitable for various motor drive scenarios. Users can select the appropriate material according to the specific motor power and phase current.
