 LED Linear Current Driver, 12 Channels, 60 mA,I2C Controllable

制造商:ON

中文数据手册

产品信息

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 (PWM) programmable via I2C serial interface. 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 2 different 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.
