South Portland, Maine—Extending the Smart Power Module portfolio to higher power commercial and industrial inverter motor applications, Fairchild's 50-amp FSAM50SM60A and 75-amp FSAM75SM60A deliver up to 5 and 7.5 kW service for air conditioners and factory automation.
"Fairchild's new Motion-SPM products enable designers to easily upgrade 1 kW-rated applications to 7.5 kW simply by selecting a different SPM device in the same ultra-compact DIP package," said Taehoon Kim, vice president of the Functional Power Group. "By using (our) thermally optimized technology, Fairchild was able to develop all 10- to 75-amp modules in one 60-by-31 mm package outline. This gives designers the ability to use significantly less board space than discrete solutions and the flexibility to simplify their designs."
Each Motion-SPM, working at up to 20 kHz to optimize power efficiency, integrates six IGBTs, six freewheeling diodes, three HVICs, one LVIC, and one thermistor. The built-in HVICs provide a single-grounded power supply for an optocoupler-less interface, while the low-side sense IGBTs provide adjustable short-circuit current protection. Each module also offers integrated sensorless control and temperature monitoring and an integrated thermistor monitors over-temperature conditions.
The 600-volt rated FSAM50SM60A and FSAM75SM60A modules, in dual-in-line (DIP) packages, occupy about half the board space of discrete solutions. Its direct bonded copper (DBC) substrate technology is designed to optimize thermal resistance and heat transfer capability.
The FSAM50SM60A and FSAM75SM60A are lead (Pb)-free products that meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with the European Union requirements now in effect.
