CAT4109 Datasheet 3-channel Constant-current Rgb Led Driver

Manufacturer: onsemi

Overview: 3-Channel Constant-Current RGB LED Driver with Individual PWM Dimming CAT4109,.

General Description

The CAT4109/CAV4109 is a 3−channel constant−current LED driver, requiring no inductor.

LED channel currents up to 175 mA are programmed independently via separate external resistors.

Low output voltage operation of 0.4 V at 175 mA allows for more power efficient designs across wider supply voltage range.

Key Features

  • 3 Independent Current Sinks up to 175 mA rated 25 V.
  • LED Current Set by External Low Power Control Resistors.
  • Individual PWM Control per Channel.
  • Low Dropout Current Source (0.4 V at 175 mA).
  • Output Enable Input for Dimming.
  • “Zero” Current Shutdown Mode.
  • 3 V to 5.5 V Logic Supply.
  • Thermal Shutdown Protection.
  • 16.
  • lead SOIC Package.
  • CAV Prefix for Automotive and Other.
