Lumissil LED Matrix manager for adaptive beam headlights
Twelve integrated bypass switches with EMI reduction and ISO26262 ASIL-B compliance
The IS32LT3365 LED Matrix Manager, an integrated circuit (IC) designed for Adaptive Driving Beam (ADB) headlamp systems. It is a scalable solution for controlling many high brightness LEDs to create innovative LED headlamps that dynamically adjust beam patterns and intensity for improved road illumination and safety. UART communication interface compatible with CAN PHY (IS32LT3365A) and CANLITE communication interface (IS32LT3365B) are used for control and management by a host MCU.
Key features
