Analog Devices, Inc. (ADI), the latest ADP8860 white LED (WLED) backlight driver, is the first in a new family of charge pump configuration devices that extends the line of lighting management systems (LMS). The ADP8860 is designed to work with the same line of LMS products, such as the ADP5520 Lighting Management System and the ADP5588 Mobile I/O Expander, which features ambient light sensing, a highly programmable register set, and advanced fade and brightness adjustment options. Significantly reduces backlight power consumption by up to 50. This flexible architecture simplifies system designers' goal of optimizing power management for a wide range of low-power, low-voltage products that require small-sized displays and/or keyboards in consumer, medical, industrial, and instrumentation electronics. Provide backlighting.
In challenging applications such as marine and portable navigation devices, radar scanners and consumer handsets, stable display is required in a variety of lighting environments, and the ADP8860 supports I/O from 1.7 to 3.3V. The device's configurable architecture automatically detects ambient light levels, adjusts backlight brightness based on changing lighting conditions, and improves ease of use. Like other Analog Devices LMS devices, the ADP8860's LMS capability allows it to automatically determine and adjust the minimum gain required as the light changes, under the same conditions, compared to conventional charge pump devices that use the same illumination gain. It reduces power consumption by up to 50. The product also offers multi-zone lighting to support the main display and other displays, including navigation, special features, keyboards, and indicators, and significantly reduces power consumption while maintaining the necessary display level. LMS also helps to minimize processor involvement and extend the device's autonomy, which increases endurance and increases battery life by 35.
The single-chip ADP8860 features parallel configuration to control up to 7 LEDs - 6 30mA LEDs (maximum) and a 60mA LED. It also offers advanced brightness adjustment and fade/darkness. This flexibility enables independent LED control to achieve minimum/maximum current and fade/darkness times, or to eliminate the fade-out/fade-out task and save power in packet LED control. For example, a designer can configure a small set of LEDs to backlight the display and assign separate LEDs to drive keyboard illumination and network connections and charge the indicator lights. The single-chip ADP8860 backlight driver also enables system designers to quickly and easily upgrade non-LMS devices to provide the desired advanced fade and brightness adjustment while extending battery life and providing enhanced user protection in a variety of lighting conditions.
