12 Channel, 60 mA LED Linear Current Driver for Automotive Applications


  • Twelve common current programmable sources up to 60 mA
  • Independent PWM duty cycle control for each channel
  • Open LED string diagnostics and protection features
  • Low dropout operation for pre‚ąíregulator applications

The NCV7685 is designed for use in the regulation and control of LED in automotive applications and consists of 12 linear programmable constant current sources with common reference and up to 60 mA current per channel. The device can be used in microcontroller applications using the I2C interface or in stand-alone applications. It allows independent PWM duty cycle control in 128 steps for each output channel, programmable via the I2C serial interface. The NCV7683 is a part of the same products family. It integrates eight linear programmable current sources, allowing LED strings to be driven with a higher current of up to 100mA per channel.
