Linear LED Driver (Hardware Interface)
NOVOSENSE Automotive-Grade Linear LED Driver (Hardware Interface) products adopt the latest linear constant-current architecture, supporting direct battery connection with 40V surge tolerance. These devices feature high-precision current regulation and enhanced thermal dissipation.These products integrates comprehensive diagnostic protections, including LED open-circuit detection, short-circuit protection, and overtemperature protection. Control interfaces (EN/DEN/PWM/ISET pins) are provided to meet automotive lighting design requirements.Furthermore, the shunt resistor-based thermal sharing technology on the output side improves thermal performance under high-temperature operating conditions.
