Alpha and Omega Semiconductor has launched an intelligent power module for low power BLDC motor drives system such as fan motors in home appliances and air-conditioners in a surface mount package.

The AIM702H50B 500V IPM7 series consists of a three phase super junction MOSFET topology for motor drive and high voltage gate driving ICs with an integrated bootstrap circuit in a new compact surface mountable package. The MOSFETs have an RDS(on) of 4.0Ω (Max). 

“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.

The package of the intelligent power module measures 18mm x 7.5mm and has a wide input of 3 to 18V for an integrated HVIC gate driver including the bootstrap circuit. The module includes under-voltage lockout protection and integrated over-temperature protection and monitoring functions.

The AIM702H50B is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces is $2.70.
