Novosense has unveiled its latest portfolio of high-performance LED driver ICs for exterior and interior lighting. Featuring high-side and low-side linear drivers as well as integrated MCU solutions for RGB/RGBW ambient control, these ICs are said to deliver precise current regulation, advanced diagnostics and robust thermal management – enabling auto makers and Tier 1 suppliers to build safer, more energy-efficient and highly customizable lighting systems.
Channel high-side linear LED driver family
The NSL21912/16/24 series are automotive high-side LED drivers delivering 100mA per channel with 12-bit PWM dimming and support automatic thermal sharing via VS shunt resistors for high thermal performance. They also feature configurable LED fault detection, integrated electrically erasable programmable read-only memory (EEPROM) for fail-safe functions, a universal asynchronous receiver/transmitter (UART) interface up to 2Mbps and optional ASIL-B functional safety support, enabling scalable and reliable lighting solutions.
Automotive 16-channel low-side linear LED driver
Novosense’s NSL23716x is a 16-channel automotive low-side LED driver with 100mA per channel and 12-bit independent PWM dimming. It integrates programmable thermal derating, LED open-/short-circuit detection and overheat protection with automatic shutdown. Built-in OTP memory supports fail-safe safety functions, while the optional CAN PHY interface eliminates the need for an external transceiver, simplifying design and improving system reliability.
Channel automotive linear LED driver with thermal balancing
The NSL2163x is a three-channel automotive linear LED driver delivering up to 200mA per channel and operating directly from a 5V–40V battery supply. It supports thermal sharing via external shunt resistors, offers an optional low-power EN-pin version, and integrates LED open/short detection with thermal shutdown for enhanced system reliability.
Highly integrated IC for ambient lightingÂ
Integrating an ARM Cortex-M3 core and four-channel high-precision current-mode LED drivers, NSUC1500 provides 16-bit independent PWM dimming and 6bit analog dimming capabilities, and enables more accurate dimming and color mixing control while effectively compensating for lumen depreciation. Additionally, NSUC1500 is compliant with the AEC-Q100 Grade 1 and CISPR 25 Class 5 EMC standards, promising high reliability and flexibility.
