Kinetic Technologies KTD2026 & KTD2027 Constant Current LED Drivers

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.

Ten internal registers are programmed via the I2C interface with a built-in decoder allowing individual control of the LED channel On/Off state and current level. A total of 192 current levels are available for each channel from 0.125mA to 24mA with a 0.125mA step. In shutdown mode, the quiescent current is reduced to less than 1μA.

The 3-channel KTD2026 from Kinetic Technologies is suitable for RGB applications, while the 4-channel KTD2027 is ideal for RGBW applications. Both devices are available in a low profile 8-pin 1.5mm x 1.5mm x 0.5mm Ultra-Thin DFN package. The packages are Pb-free and RoHS-compliant.
