The new IPM7 series consists of advanced super junction MOSFETs designed for motor drive and high voltage gate driving ICs with an integrated bootstrap circuit in a new ultra-compact surface mountable package.

“A BLDC-based inverter has been widely used in fan motors because it is quicker, quieter, and more energy-efficient than the conventional solutions using dc motors or ac induction motors with on/off control. Nowadays, its demand and expansion are becoming a mandatory requirement due to energy saving and regulations. Without a doubt, IPM7 will bring a lot of advantages for fan motor applications by significantly enhancing the cost-effective development of the system, reducing the inverter board size, and obtaining easy and reliable PCB assembly. Quick and precise detection of fault temperature in IPM7 will play a significant role in fan motor drives to secure a reliable design as well as a long time of operation,” said Dr. Brian Suh, vice president of IGBT/IPM product lines at AOS.

IPM7 Series Technical Highlights

  • Compact package: 18mm x 7.5mm
  • 3-phase super junction MOSFET inverter topology for motor drives
  • Integrated HVIC gate driver including bootstrap circuit
  • Wide input interface (3~18V)
  • Control supply under-voltage lockout protection
  • Integrated over-temperature protection and monitoring functions

Pricing and Availability

The AIM702H50B is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces is $2.7.
