In the rapidly evolving era of electric vehicles, rear lighting systems have transformed from simple functional components into key elements that showcase brand identity and technological innovation. Today’s consumers expect more than basic signaling functions. Modern rear lights must offer high levels of customization to meet consumer demands for aesthetics and differentiation.
To address these evolving market needs, including the demand for smart, energy-efficient lighting that meets stringent regulatory standards, Nexperia launched its AEC-Q100 qualified automotive LED driver family. Featuring comprehensive safety functions and robust performance, the technology underlying these devices enhances design flexibility while optimizing energy efficiency, improving reliability and reducing overall system costs.
Reliable communications for advanced rear lighting
Modern rear lighting systems have become increasingly sophisticated, with continuous tail lamp designs spanning the width of the vehicle to create distinctive brand signatures. These architectures introduce complex wiring and extended interconnect lengths, creating significant communication challenges and placing greater demands on system robustness and EMC performance.
Traditional single-ended interfaces may struggle to provide robust off-board communication while meeting stringent EMC requirements. Fortunately external physical-layer transceivers offer a straightforward solution for reliable long-distance communication. Complementing these architectures, Nexperia's LED driver family combines a high level of integration with advanced diagnostics and comprehensive fault management, helping designers to accelerate development and bring sophisticated lighting concepts to market more efficiently.
Safety first: fault detection and protection
Nexperia's 16-channel (NEX13160/61) and 24-channel (NEX13240/41) linear LED drivers support independent PWM dimming on each channel, enabling sophisticated dynamic animations that enhance both aesthetics and functionality. Their high level of integration simplifies system design, reduces thermal management requirements and lowers overall system costs.
| Type number | Detail |
|---|---|
| NEX13160PE-Q100 | 16-channel + UART |
| NEX13161PE-Q100 | 16-channel + CAN |
| NEX13240PE-Q100 | 24-channel + UART |
| NEX13241PE-Q100 | 24-channel + CAN |
They also feature advanced diagnostic and fault-protection capabilities. These capabilities include real-time monitoring of fault and status flags via UART, configurable fault management, and diagnostic functions for open circuits, short-to-ground faults and single-LED short circuits. Additionally, internal clock monitoring and a configurable watchdog ensure the system transitions to a fail-safe state in the event of MCU communication interruptions, further enhancing safety and reliability.
As electric vehicle designs continue to evolve, the NEX13160/61 and NEX13240/41 will enable increasingly distinctive, intelligent and reliable rear-light systems. Explore how Nexperia's highly integrated multi-channel Automotive LED drivers support next-generation EV rear lighting with dynamic animations, functional safety and EMC robustness.
