SC620  
Octal LED Driver, General Purpose  
Current Sink with Serial Interface  
POWER MANAGEMENT  
Features  
Description  
The SC620 is a multi-purpose LED driver with eight identi-  
cal, independently controlled current sinks. Each current  
sink can drive an LED by connecting the LED’s anode to  
the system power supply and the cathode to the current  
sink input pin. Any combination of outputs can be enabled  
or disabled for optimal design flexibility.  
ꢀ Eight identical current drivers with independent  
control  
ꢀ Wide current setting range - 31.25μA to 25mA  
ꢀ 3% current matching, 5% accuracy  
ꢀ I2C interface for microprocessor control  
ꢀ I2C slave address 1110 000x  
ꢀ Less than 1μA quiescent current in shutdown  
ꢀ Low dropout voltage: ≤ 150mV  
ꢀ Over-temperature protection  
ꢀ MLPQ-UT-16 package (3mm x 3mm)  
ꢀ Ultra-thin 0.6mm maximum package height  
ꢀ Fully WEEE and RoHS compliant  
In addition to the individual current settings, the SC620  
employs an adjustable global current gain setting register  
to allow the current setting step size to vary from 31.25μA  
to 500μA, giving the designer a wide range of options for  
LED variation and dimming functions. The maximum output  
is also scaled by this step size, with a maximum of 25mA  
at the highest step setting.  
Applications  
ꢀ LCD backlighting LED driver  
ꢀ Multicolor and RGB LED driver  
ꢀ General purpose current sink array  
ꢀ General purpose digital output (open-drain) expander  
ꢀ Auto-focus voice-coil driver  
Multi-colored and white LEDs with different forward volt-  
ages can be driven using the same SC620 due to its floating  
cathode technology. This feature allows each output pin to  
vary in voltage from 150mV to VIN - 1.5V.  
All current control is done via an I2C interface bus. Only a  
single input bypass capacitor is required - no other exter-  
nal resistors or capacitors are needed. The 3mm x 3mm  
MLPQ package and minimal support components make  
the SC620 an ideal solution for low-cost, area-conscious  
backlighting designs.
