Kinetic Technologies KTD2026 and KTD2027 Constant Current LED Drivers are fully programmable with a flexible I2C control interface. The devices are ideally powered from one-cell lithium-ion/polymer, 3-cell NiCd/NiMH/Alkaline batteries, or systems with 3.3V or 5V supplies. The independent programmable constant current sinks operate without external components. With an on-chip timing control unit, LED blink rate, fade-in, and fade-out are user-adjustable, resulting in unique color lighting patterns.
