ADP8860 - Charge Pump, 7-Channel Smart LED Driver with I2C Interface
ADI offers LED drivers for automotive and LCD-backlighting applications. Products like the AD8240, designed for automotive applications, both drive and monitor the LED assembly. The AD8240 lowers system cost by reducing the complexity associated with LED driving, includes overcurrent protection, and is available in a MSOP package. The ADM8845 charge pump is designed for driving up to six white LEDs in parallel while ensuring uniform brightness of a backlit LCD display. By individually monitoring each LED current, excellent matching performance is achieved. The ADM8845 is also designed to maximize power efficiency by switching automatically between three charge pump modes based on the input voltage.
