4 Channel Led Driver

  The AHK3294 is a linear current-sink LED driver, capable of driving one, two, three or four LEDs up to 30.2mA each. Featuring individual low resistance, low drop-out voltage current sinks, the AHK3294 allows the LEDs to be regulated directly from a Lithium Ion/Polymer Battery without the need for an additional Step-up power supply, thereby reducing the external component count, elimi- nating switching noise and maximizing efficiency. AnalogicTech?s Simple Serial Control? (S2Cwire?) inter- face is used to enable, disable, and set the LED drive cur- rent for 32-level linear scale LED brightness control. For flexible control the maximum LED current of up to 30.2mA per channel is set via an external Resistor The AHK3294 is packaged in a Pb-free, 8 pin SC70JW package and is available over a -40 to +85OC tempera- ture range.
