LED Drivers

16-channel LED driverconstant-current sink16-bit PWMVQFN-32LED open detection

TLC5943RHBR is a 16-channel constant-current LED sink driver with 16-bit PWM control and a shared 7-bit brightness-current setting.

Best for

  • 16-channel LED display drivers
  • LED signboards and display backlighting
  • Applications requiring high-resolution PWM dimming

Avoid if

  • Per-channel analog current adjustment is required
  • The design cannot provide a GSCLK source
  • Thermal dissipation cannot support active-channel current

Check before use

  • RIREF value and resulting maximum output current
  • VCC range of 3.0 V to 5.5 V
  • LED supply/output voltage up to 17 V
  • VQFN-32 thermal-pad PCB implementation
