DC-DC Converter

      SQM50A65JC is a highly integrated and highly reliable three-phase brushless DC motor drive circuit, which is mainly used in high-power frequency conversion drives, such as auto air conditioners, inverters, etc. It contains 6 low loss IGBTs and 3 half-bridge HVIC for gate driving.

      SQM50A65JC integrates various protection functions such as undervoltage and short circuit, as well as temperature output, providing excellent protection and a wide safe operating range. Since each phase has an independent negative DC terminal, its current can be sensed separately. 

      SQM50A65JC is designed with good insulation and perfect thermal properties. It is compact and suitable for built-in motors or any other applications requiring the compact installation.


Main feature
  • Built-in six 650V/50A low loss IGBTs 

  • Built-in high-voltage Gate driver circuit (HVIC)

  • Built-in under voltage protections, over current protection and NTC temperature detection

  • Compatible with 3.3V, 5V MCU interface, active high

  • Three independent negative DC terminals for inverter current detection

  • Alarm signals: corresponding to low-side undervoltage protection, , and short-circuit protection

  • Package: Utilizes a Direct Bonded Copper (DBC) design, which provides an exceptionally low thermal resistance.

  • Insulation class: 2500Vrms/min
