NCV7685

12 Channels 60 mA LED Linear Current Driver I2C Controllable for Automotive Applications NCV7685 The NCV7685 consists of twelve linear programmable constant current sources with common reference. The part is designed for use in the regulation and control of LED for automotive applications. The NCV7685 allows 128 different duty cycle levels adjustable using pulse width modulation (PWM) independently for each output channel programmable via I2C serial interface. PWM frequency can be chosen in four different configurations up to 1200 Hz. The device can be used with micro−controller applications using the I2C bus or in stand−alone applications where a choice could be done in between two different static configuration settings. The IC also provides 3.3 V voltage reference to the application for loads up to 1 mA. LED brightness level is easily programmed using an external resistor. Each channel has an internal circuitry to detect open−load conditions with an optional auto−recovery mode. If one driver is in open−load condition, all other channels could be turned off according to the programmable bit setting. The device is available in small body size SSOP24−EP package.
