Semtech SC620
Current Sink LED Driver for 8 BL + I2C Interface
The SC620 is a multi-purpose LED driver with eight identical, independently controlled current sinks. Each current sink can drive an LED by connecting the LED’s anode to the system power supply and the cathode to the current sink input pin. Any combination of outputs can be enabled or disabled for optimal design flexibility.
