2 / 14 page Apr20-07 RevS SP7611A/7612A/7614A Low Dropout Linear LED driver 2007 Sipex Corporation Page 2 ABSOLUTE MAXIMUM RATINGS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. ELECTRICAL SPECIFICATIONS Specifications are at TA=25°C, VIN = 3.3 to 5.5, ENABLE =VIN, ♦ denotes the specifications which apply over the full operating temperature range, unless otherwise specified. PARAMETER PART # MIN TYP MAX UNITS ♦ CONDITIONS LED Cathode Voltage (VLED) 5.5 V See graph for LED Current vs. Cathode Voltage Ambient Temperature -40 20 85 ºC SP7611A SP7612A ISET = 100µA VLED = 300mV Output Current Multiplication Ratio in Saturation (Note1) SP7614A 140 200 260 ISET = 100µA VLED = 150mV SP7611A SP7612A 365 435 505 Output Current Multiplication Ratio (Gain) (Note1) SP7614A 730 870 1010 ISET = 25µA VLED = 0.5V LED to LED Current Matching -3 0.8 3 % Â ♦ ISET = 100µA VLED = 300mV Current in OFF Mode 0.01 1 µA Â ♦ VENABLE = 0.0V Min. ENABLE ""ON Voltage" (Note 2) SP7612A SP7614A 3 V Â ♦ ISET = 150µA Max. ENABLE ""OFF Voltage" (Note 2) SP7612A SP7614A 0.5 V Â ♦ Note 1: Output current Multiplication Ratio (ILED/ISET) is not linear. For actual ratio and ILED please refer to typical performance characteristics on pages 4 through 7. Note 2: ENABLE "ON" is VON/OFF where ILED1 > 20mA @ VLED1 = 0.3V. ENABLE "OFF" is V where I < 1µA @ V > 0.3V.
