Designers of motor control systems need solutions that optimize efficiency and ensure maximum reliability under harsh application conditions. To meet this challenge, Fairchild Semiconductor developed the SPM 5 smart power module series 3-phase MOSFET inverter solution, providing designers an AC induction motor (ACIM) and Brushless DC (BLDC) motor inverter solution for motors up to 200W including fan motors, dish washer pumps, and various small industrial motors.
The new SPM 5 series is composed 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 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.
This new SPM series features three bootstrap diodes in a tiny 29mm x 12mm package rated for 250V, 500V and 600V operation. The compact design and simple electrical interface make it ideal 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 today’s applications require.
