NCV7680: LED Driver for Automotive LED Rear Combination Lamps

Description: The NCV7680 consists of eight linear programmable ...
  • The NCV7680 consists of eight linear programmable constant current sources. The part is designed for use in the regulation and control of LED based Rear Combination Lamps for automotive applications. System design with the NCV7680 allows for two brightness levels, one for stop and one for tail illumination, or optional PWM control can also be implemented.
    Discrete LED brightness levels are easily programmed (stop current value, tail duty cycle value) optional external ballast FET allows for power distribution on designs requiring high currents. Set back power limit reduces the drive current during overvoltage conditions. This is most useful for low current applications when no external FET is used.
  • Features
  • Constant Current Outputs for LED String Drive - LED devices are best controlled with current drive due to their exponential voltage characteristics
  • LED Drive Current up to 75mA per Channel - Sufficient drive for most popular low current LED devices
  • Open LED String Diagnostic with Open-Drain Output - System functionality back to the microprocessor
  • Slew Rate Control - Eliminates EMI concerns
  • Low Dropout Operation - Maintains functionality during drops in automotive battery voltage
  • External Modulation Capable - Flexible for many system operation setups
  • On-chip 1 kHz Tail PWM Dimming - Simplifies system design.
  • Stop Current Set Point programmability - Easy programmability with one resistor
  • Tail Dimming Set Point programmability - Easy programmability with one resistor
  • Overvoltage Set Back Power Limitation - Keeps IC temperature lower at extended voltage range.
  • Pb-Free - Meets lead free regulations
