onsemi LED Drivers NCV7685DQR2G

The NCV7685DQR2G is a 12-channel linear current driver designed for automotive applications, capable of providing up to 60 mA per channel. It features programmable constant current sources with a common reference, allowing for independent control of each channel's duty cycle through pulse width modulation (PWM) via an I2C interface. The device supports four selectable PWM frequencies, up to 1200 Hz, and can be configured for both microcontroller applications and stand-alone operation with two static settings. This LED driver includes diagnostics for open-load conditions, with an optional auto-recovery mode, and can disable other channels if one is in an open-load state. It also features a 3.3 V voltage reference for loads up to 1 mA, low dropout operation, and over-temperature protection. The NCV7685DQR2G is housed in a compact SSOP24-EP package and is AEC-Q100 qualified, making it suitable for automotive environments. Applications include dashboard lighting, rear combination lamps, daytime running lights, and fog lights.
