NCV78763DQ6AR2G

The NCV78763DQ6AR2G from On Semiconductor is a versatile, single-chip solution for automotive front lighting systems. This smart power ballast and dual LED driver is engineered for high efficiency and can manage two LED strings, each up to 60V. It offers a high current capability of 1.6A DC per output, making it suitable for demanding applications like high beam, low beam, daytime running lights (DRL), turn indicators, and fog lights.

The device integrates a current-mode voltage booster controller and a switched-mode buck current regulator, minimizing the need for external components and reducing Bill of Materials (BOM) cost. Its SPI programmability allows for flexible system configurations, supporting a platform solution approach. The NCV78763DQ6AR2G features active input filtering for low current ripple from the battery, integrated PWM dimming with a wide frequency range, and low EMC emissions. It is available in a 36-SSOP-EP package and is designed for surface mount installation.

This LED driver is ideal for automotive front lighting, providing customizable output current and voltage for individual LED channels. On-chip diagnostic features aid in safety monitoring by the microcontroller. When more than two LED channels are required, multiple NCV78763 devices can be combined, potentially operating in multiphase mode for optimized filtering and cost-effective dimensioning of mid to high-power LED systems.
