NCV7680PWR2G

The NCV7680PWR2G is an integrated circuit from On Semiconductor designed for the regulation and control of LED-based Rear Combination Lamps in automotive applications. It features eight linear programmable constant current sources, each capable of driving LEDs up to 75 mA per channel.

This device supports two brightness levels for stop and tail illumination, with optional PWM control. It includes on-chip 1 kHz tail PWM dimming and allows for discrete LED brightness levels to be programmed via single resistors for stop and tail current set points. An optional external ballast FET can be used for power distribution in high-current designs.

The NCV7680PWR2G also incorporates features such as open LED string diagnostics with an open-drain output, slew rate control to minimize EMI concerns, and low dropout operation suitable for pre-regulator applications. It includes overvoltage set back power limitation to reduce drive current during overvoltage conditions.

Packaged in a 16-lead SOICW with an exposed pad, this Pb-Free device is AEC Q100 qualified, making it suitable for demanding automotive environments. Applications include Rear Combination Lamps (RCL), Daytime Running Lights (DRL), Fog Lights, Center High Mounted Stop Lamps (CHMSL) Arrays, and Turn Signal applications.
