Description

The AHK3292 is a linear current-sink LED driver, capable of driving one or two LEDs up to 30.2mA each. Featuring individual low resistance, low drop-out voltage current sinks, the AHK3292 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, eliminating switching noise and maximizing efficiency.

AnalogicTech Simple Serial Control™ (S2Cwire™) interface is used to enable, disable, and set the LED drive current for 32-level linear scale LED brightness control. For maximum flexibility the LED current can be set, up to a maximum of 30.2mA per channel, using an external RSET resistor.The AHK3292 is packaged in a Pb-free 6-pin SOT23 package and is available over a -40 to +85OC temperature range.
