Linear LED Driver (Digital Interface)
NOVOSENSE Automotive-Grade Linear LED Driver (Digital Interface) products adopt the latest linear constant-current architecture, featuring high current regulation accuracy and strong thermal performance. They are available in both high-side and low-side configurations.These products support comprehensive diagnostic protection functions, including LED open-circuit, LED short-circuit, overtemperature protection, and other diagnostic features. The full product series supports UART digital interfaces, with select models integrating CAN PHY to simplify cross-board communication design.Through the built-in memory unit (MTP or OTP), NOVOSENSE' Automotive-Grade Linear LED Driver (Digital Interface) products enable Fail Safe operating states, ensuring continued operation under preset conditions even during communication loss to meet safety requirements.Additionally, these products incorporate NOVOSENSE' innovative VS shunt thermal sharing feature, significantly simplifying thermal sharing design for multi-channel linear LED drivers.
