The SPF5047 is a bypass switch for the highbrightness matrix LEDs used in applications such as automotive headlights. The product includes four series switches to bypass individual LEDs, whose dimming systems are externally controlled by a CPU. Each LED has open and short detections that can send fault flags to the CPU. Even if one of the four LEDs becomes open, the open-LED is bypassed by its built-in power MOSFET so that other LEDs can continue to work normally. The SPF5047 is supplied in a compact, surface-mount type HSOP package, with an exposed pad for enhanced thermal dissipation.

Features

    ・4 Series LED Bypass Switches
    ・Drives Up to 16 LEDs in Series (with 4 ICs; at VF of an   LED is approx. 3 V)
    ・Low Noise:
      No charge-current-induced noise occurs as each gate driver   uses a negative power source which requires no   charge-pump circuit.
    ・High Efficiency:
      Optimized trade-offs between switching loss and switching   noise allow highly-accurate control in tr and tf.
    ・Fault Flag Reporting
    ・LED Open Detection
    ・LED Short Detection

Application

・Automotive Headlight
・Daylight Running Lamp (DRL)
・High-Brightness Matrix LED System
