ON Semiconductor NCV7680PWR2G LED Driver IC

The NCV7680PWR2G is a versatile LED driver integrated circuit (IC) designed and manufactured by ON Semiconductor, a renowned leader in the semiconductor industry. This high-performance IC is tailored for automotive lighting applications, specifically engineered to manage multiple LED configurations with efficiency and reliability.

Constructed with precision, the NCV7680PWR2G is a linear programmable current regulator capable of supplying a continuous output current to an array of LEDs. Its output current can be programmed via an external resistor, giving designers the flexibility to adjust the current according to the specific needs of their LED applications. This feature is particularly useful for tailoring the brightness levels in automotive rear lighting and interior lighting systems.

The device operates over a wide input voltage range from 5V to 40V, making it suitable for a variety of automotive power systems. It can withstand load dump transients up to 45V, which is a critical requirement for automotive power supplies, ensuring that the IC can handle the harsh electrical environment within vehicles.

The NCV7680PWR2G incorporates eight linear programmable constant current sources (CCS) for LED string drive, each capable of driving up to 75 mA. The current sources can be connected in parallel to provide higher currents to a single string of LEDs. Additionally, the IC includes built-in open LED detection and LED thermal foldback features, enhancing the safety and longevity of the lighting system by preventing damage due to excessive heat or open circuit conditions.

With its thermal shutdown protection mechanism, the NCV7680PWR2G ensures safe operation by turning off the output current when the junction temperature exceeds the thermal shutdown threshold. This feature helps to safeguard the IC and the LEDs it drives from overheating.

Offered in a compact 24-pin SOIC package, the NCV7680PWR2G is designed for space-constrained applications, providing a compact and efficient solution for automotive LED driving requirements. Its robust design and feature set make it an ideal choice for designers looking to create reliable, high-quality automotive lighting solutions.
