Programmable 3-ch LIN RGB Driver The TLD4020-3ET is a three channel device with integrated and protected output stages. It is designed to control RGB LEDs with a current up to 51.5 mA as linear current sink (LCS). The power stages can be configured in parallel for higher load currents. Each individual power output stage is configurable via a 5-bit current set value. In total 3 independent and individual PWM configurations can be set. A LIN interface is used for programming (via bootloader), control and diagnostic feedback.
