Alpha and Omega Semiconductor Limited announced the release of a newintelligent power module, AIM702H50B, specialized for low-power BLDC motor drives system such as fan motors in home appliances and air-conditioners that require highly compact size with reliable and efficient design allowance.
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/IPMproduct linesat 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 includingbootstrap circuit
