Description

The FAN5611/12/13/14 low-dropout product family is

designed to drive two to four parallel LEDs, providing

matched current source bias for all color LEDs. The LED

current is set by an external resistor, RSET. The

FAN5611/13 supports four parallel LEDs with up to

160mA bias current (up to 40mA per output). The

FAN5612 supports three LEDs with up to 120mA bias

current (40mA per output). The FAN5614 drives two

high-current LEDs (80mA per output). Pin I1 should

always be connected to an LED to provide a matched

current for any additional LEDs.

The FAN5612/13 and 14 are selected using an ENABLE

pin. When the chip is not selected (ENABLE

pin is

LOW), the supply current drops to less than 1µA.

The FAN5611, FAN5612, and FAN5614 are available in

an SC-70 package. The

FAN5611 and FAN5613 are

available in MLP packages.
