| (R) ADVANCED PREPARED FOR SAGEM SP7614 Low Dropout LED Driver for any Color LED FEATURES LED Drivers for parallel connected LEDs Low Dropout Voltage(<300mV) to support direct Li-ion applications No EMI, no switching noise No external components needed for current matching PWM and Analog brightness control 160mA bias current (up to 80mA for each LED) Enable/Shutdown control Shutdown current < 1A Small footprint SC-70 Package APPLICATIONS Next Generation Mobile Phones PDA, DSC, MP3 players Handheld Computers LCD Display Modules Keyboard Backlight LED Displays DESCRIPTION The SP7614 driver family provides matched current source bias for white, blue or any color LEDs. The current in the LEDs can be programmed by an external resistor. The Individual LED currents are 200 x ISET, where ISET is the current through the external resistor connected to the CTRL pin. The SP7614is designated to drive two high current LEDs. The SP7614 is offered in a 6pin SC-70 package.
