NCV7684 12 Channels 60 mA LED 2 Linear Current Driver I C Controllable for Automotive Applications www.onsemi.com The NCV7684 consists of twelve linear programmable constant current sources. The part is designed for use in the regulation and control of LED for automotive applications. The NCV7684 allows 128 different current levels adjustable with pulse width modulation 2 (PWM) programmable via I C serial interface. The device can be used SSOP24 NB EP 2 with microcontroller applications using the I C bus or in standalone CASE 940AP applications where a choice could be done in between 2 different configuration settings. The IC also provides 3.3 V voltage reference to the application for loads up to 1 mA. MARKING DIAGRAM LED brightness level is easily programmed using an external resistor. Each channel has an internal circuitry to detect openload conditions with an optional autorecovery mode. If one driver is in XXXXXXXXXG openload condition, all other channels could be turned off according AWLYYWW to the programmable bit setting. The device is available in small body size SSOP24EP package.
