DataSheet.in FAN5622/24/26 — Linear LED Drivers with Single-Wire Digital Interface May 2010 FAN5622 / FAN5624 / FAN5626 Linear LED Drivers with Single-Wire Digital Interface Features ƒ ƒ Family of Three Linear Current-Sink LED Drivers that Support 2, 4, or 6 LED Outputs Current Sink Driver for Each LED Output: – 30mA Maximum Output Current – 50mV Drop-out at 15mA IOUT – Better than 3% Matching between Channels – External RSET Single-Wire Digital Control Interface for Easy Programming – 32 Linear Steps of Dimming Control Less than 1µA Shut-Down Current Short-Circuit, Under-Voltage, and Thermal Protection Wide Input Voltage Range: 2.7 to 5.5V Small Form-Factor Packages: – FAN5622: 6-pin Super SOT23 – FAN5624: 10-lead 1.4x1.8x0.55mm UMLP – FAN5626: 10-lead 1.6x2.1x0.55mm MicroPak™ MLP Description The FAN5622, FAN5624, and FAN5626 are two-, four-, and six- channel current-sink linear LED drivers used to backlight the main LCD displays or keypads in mobile electronics, such as cellular phone handsets. A very low dropout of 50mV allows driving LEDs without any inductors or switch capacitors. The brightness levels of the LED outputs are programmed through single-wire digital control interface. The user can program 32 linear dimming steps and turn on and off the LEDs through this interface by applying digital pulses. The FAN562x family of linear LED drivers provides high efficiency due to the low drop-out voltage of the LED driver. Good matching between different channels of LED ...
