Semtech SC667

7 LED Light Management Unit Automatic Dropout Prevention, Ambient Light Sense Input, PWM Dimming, and 4 LDOs


The SC667 is a highly integrated light management unit that provides programmable current for up to seven LED current sinks. Four LED banks are provided to allow settings for various LED zones or indicators. Four low-noise LDOs with programmable outputs ranging from 1.2V to 3.3V and 200mA maximum output current are also included.


  • Seven LED backlight sinks with 32 current settings from 0mA to 25mA
  • Up to four LED backlight banks
  • Lighting effects — fade-in/fade-out, breathe, blink, auto-dim full, and auto-dim partial functions
  • ADP (Automatic Dropout Prevention) for backlights
  • ALS (Ambient Light Sense) option sets the backlight brightness according to ambient lighting conditions
  • I2C Bus fast mode and standard mode
  • IRQ (Interrupt request) — open-drain output indicates a change of state for the ALS
  • Backlight current accuracy — ±1.5% typical
  • Backlight current matching — ±0.5% typical
  • Four programmable 200mA low-noise LDO regulators
  • PWM interface (200Hz to 50kHz) with internal digital low-pass filter
  • Automatic sleep mode with all LEDs off
  • Shutdown current — 0.1μA typical
  • Ultra-thin package — 3 x 3 x 0.6 (mm)
  • Lead-free and halogen-free
  • WEEE and RoHS compliant
