San Jose, CA — Designers of motor control systems need solutions that optimize efficiency and ensure maximum reliability under harsh application conditions. To meet this challenge, Fairchild Semiconductor (NYSE: FCS) developed the SPM 5 smart power module series 3-phase MOSFET inverter solution, providing designers with an AC induction motor (ACIM) and Brushless DC (BLDC) motor inverter solution for motors up to 200W including fan motors, dishwasher pumps, and various small industrial motors.

The new SPM 5 series is comprised of six fast-recovery MOSFETs, and three half-bridge HVICs for gate driving. The devices provide low electromagnetic interference (EMI) characteristics with optimized switching speed.
Precision driving of the low RDS(ON) MOSFETs minimizes EMI and maximizes switching efficiency. The integrated under-voltage lockout and thermal sensing unit provide local protection to the SPM device while allowing the attached controller IC to monitor the module's thermal performance in real time.
Part of the Motion SPM 5 SuperFET® series, the FSB50x60SF(S) devices are based on 600V Super Junction MOSFET technology, while the FSB50xxxA(x) are based on 250V/500V FRFET® technology. The SPM 5 SuperFET series is reportedly the industry's first 600V super junction MOSFET module solution for small home appliances and small industrial drives. Both technologies provide better ruggedness and larger safe operation area (SOA) than that of an IGBT-based power module or one-chip solution.
The new SPM series uses three bootstrap diodes in a tiny 29 x 12mm package rated for 250V, 500V and 600V operation. The compact design and simple electrical interface make it suitable for applications requiring a small footprint, rapid time-to-market and design scalability, such as built-in motor applications, and any other application where the assembly space is limited. Devices in the series provide designers the energy efficiency, compactness, and low EMI that today's applications require.
Also available to designers is Fairchild's Motion Control Design Tool, an online resource that calculates power losses and temperature fluctuations to optimize heat sink selection and ultimately system costs.
