MADD-08898A-Q

4-channel 2A LED/Laser Driver for Automotive Head Up Displays (HUD)

 The MADD-08898A-Q is an AEC-Q100 qualified high efficiency integrated LED/laser driver for Automotive Head Up Displays (HUD) and LCD/LCoS/TI DLP® projection displays. Each of the four channels may drive up to 2 A. Color mixing is register selectable and the correct LED drive current is automatically loaded and the DC-DC converter can be programmed to always adjust its output for the LED with the highest forward voltage. A single DC-DC converter can be used to supply all 4 outputs or as many as 4 external DC-DC converters can be controlled to generate the optimal LED bias voltages. Safety Circuitry features include over-temperature and over-voltage monitoring. The MADD-08898A-Q features also fully programmable PWM current generator. The part is programmed via I2C and a standalone EEPROM port allows automatic loading of internal registers with minimal microcontroller overhead.
