ET6326中文资料3CH with Auto-Breathing数据手册ETEK规格书

描述 Description

The ET6326 is a constant current RGB LED drivers with I2C interface. The devices are ideally powered from one-cell lithium-ion/polymer, 3-cell NiCd/NiMH/Alkaline batteries, or 3.3V~5V supplies. The independent programmable constant current sinks operate without external components. By the nine internal registers programming, the three LED channels can work in variety modes, a total of 192 current levels are available for each channel from 0.125mA to 24mA with a 0.125mA step.The device has design three kinds of interconnected threads, each channel can carry on any thread. With an on-chip timing control unit, LED blink rate, fade-in and fade-out are user-adjustable resulting in unique color lighting patterns.In shutdown mode, the quiescent current is reduced to less than 1μA. The driver is available in a small DFN8 package. The package is Pb-free and RoHS compliant.
