The AAT2861 is a highly integrated charge pump-based lighting management unit (LMU) offering eight LED channels with three linear regulators optimized for single- cell lithium-ion/polymer systems. The charge pump provides power for all LED outputs; multiple backlight and flash LED configurations are available. The backlight LED outputs can be programmed up to 31mA each and the flash LED output current can be programmed up to 600mA total. AnalogicTech’s AS²Cwire™ (Advanced Simple Serial Control™) single-wire interface is used to enable, disable, and set the current to one of 32 levels for the backlight and one of 16 levels for the flash. A programmable safety timer and separate flash control input are included for easy flash control. Backlight current matching is better than 3% for uniform display brightness, and flash current matching is better than 5% for uniform power dissipation. The AAT2861 also offers three high-performance low-noise MicroPower™ LDO linear regulators. The regulators output voltages are set through the AS²Cwire serial interface. Each LDO can supply up to 300mA load current and ground-pin current is only 80µA, making the AAT2861 ideal for battery-operated applications. The AAT2861 is available in a Pb-free, space saving TQFN34-24 package and operates over the -40°C to +85°C ambient temperature range.
