Recommended Product Solutions

  • Integrated Solutions (SPM)
    • Motion SPM® (Smart Power Module) - integrated drive and protection in a single package. Simplify and accelerate your design as you optimize efficiency. These devices are sometimes referred to as Intelligent Power Modules (IPM) by the market.
  • Discrete Solutions (Discretes)
    • HVICs (High Voltage Integrated Circuits) are MOSFET and IGBT gate drivers. These stand-alone HVICs save 50% PCB area compared to commonly used optocoupler-based or pulse transformer-based solutions.
    • IGBTs (Insulated Gate Bipolar Transistors)
    • MOSFETs
  • BLDC / PMSM Controller (Brushless DC / Permanent Magnet Synchronous Motor)
    • Mixed signal IC (Integrated Circuit) exclusively for motor control; e.g. hardware implemented fault detection, replaces complicated DSP (Digital Signal Processor), and more features. No complicated software development required.
    • Advanced Motor Controller (AMC) can adopt various configurable libraries for different application requirements; e.g. Sensorless Field-Oriented Control (FOC) with Speed Integral Method, Sensorless FOC with Sliding Mode.
    • MCU Embedded to increase flexibility for peripheral controls and communications.
  • Power Factor Correction (PFC)
    • PFC-SPM (Smart Power Module) - front-end rectifier circuit specifically designed to minimize input current distortion and make the AC-in current in phase with the AC-in voltage; e.g. reduce power loss. Save energy = Save money.
    • PFC controller IC's for discrete PFC implementation: Continuous Conduction Mode (CCM ) and Critical/Boundary Conduction Mode (CrCM / BCM) PFC controllers.
  • Optoelectronics
    • Optoelectronics complement Fairchild's well-established offering in the discrete power IGBT/MOSFET line of products. Optoelectronics are used in motor control designs to provide isolation from high voltage devices.
  • Switched Mode Power Supply (SMPS)
    • Demonstrated here are power management devices used in flyback converter design, the most popular Switch Mode Power Supply (SMPS) topology.  These off-line power switches are integrated Pulse Wave Modulation (PWM) controllers with an integrated fully avalanche-rugged SenseFET™ and current mode PWM control block.
  • Bridge Rectifiers
    • Fairchild has a wide range of Bridge Rectifier packages based on power dissipation needs. This landing page will list our single package bridge rectifiers which can easily be mounted on a heat sink for high voltage applications.
