Lighting System Touts 20 Percent Battery Consumption Reduction
Tue, 11/04/2008 - 6:30am
Enabling an up to 20 percent reduction in battery power consumption through the use of an “intelligent” lighting-control, the single-chip ADP5520 lighting management system from Analog Devices automatically detects ambient light levels and adjusts backlight brightness according to changing lighting environments. The lighting system can also assume control of key-scan and general-purpose I/O sub-system functions from the processor. The device is housed in a 24-pin LFCSP (lead-frame chip-scale package) and operates with a 2.7 v- to 5.5-V supply voltage and a 1.8-V to 3.3-V I/O supply. The ADP5520 is priced at $1.66 per unit in 1,000-unit quantities.
