The regulated LED current from each output is set by a single reference resistor. Current matching in each string is achieved without the need of ballast resistors. Dual control pins are available for both switch (on/off) and master control (on/off/dim up/dim down) signals. Outputs can be connected in parallel or left unused as required. Short detection is provided to protect the LEDs and the device during a short-to-ground at any LED output pin. The output will automatically resume the regulated current when the short is removed. A temperature monitor is included to reduce the LED drive current if the chip temperature exceeds an adjustable thermal threshold.

The A6269KLJTR-T is available in an 8-pin narrow SOIC package with exposed pad for enhanced thermal performance.
