8-channel LED driverconstant-current sinkAEC-Q100SOIC-16serial LED driverload diagnostics

TLC5917QDRQ1 is an automotive-qualified 8-channel constant-current LED sink driver for serially controlled LED strings and displays.

Best for

  • Automotive LED indicators and lighting
  • Cascaded LED display channels
  • Applications needing open-load, short-load, and thermal diagnostics

Avoid if

  • LED strings requiring more than 17 V at an output pin
  • Applications requiring independently programmable current per channel

Check before use

  • R-EXT value and default/current-gain configuration
  • LED forward-voltage tolerance and output compliance voltage
  • Thermal rise with all active channels
  • Special-mode diagnostic timing
