Description

General part information

FAN5701 Series

The FAN5701 is a highly integrated and efficient chargepump- based multi-LED driver. The device can drive up to six LEDs in parallel with a total output current of 180 mA.The FAN5701 is capable of driving a primary display backlight requiring four to six LEDs. When more than four LEDs are needed for backlighting, the FAN5701’s two PWM dimming inputs can be connected together to provide the proper dimming control for all six LEDs. When a primary and sub-display is needed, the FAN5701 can be controlled such that each group can be dimmed independently. For candybar phones requiring a primary display and simple keypad lighting, the FAN5701 offers a simple and compact lighting solution.Regulated internal current sinks deliver excellent current and brightness matching to all six LEDs. The device provides excellent efficiency without an inductor by operating the charge pump in 1.5x or pass-through modes.The FAN5701 can be ordered with default ISETvalues of 30 mA, 20 mA, 15 mA, or 8 mA. The default ISETis always determined by the part number purchased.
