Infineon First LITIX™ Interior TLD4020-3ET

The TLD4020-3ET is an automotive LED driver 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). It comes with an integrated 32-Bit Arm^® Cortex^®-M23 MCU for optimal color calibration. 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 control and diagnostic feedback.
