SC623  
LED Light Management Unit  
Charge Pump, 4 LEDs, 400mA Flash LED,  
and SemWireTM Interface  
POWER MANAGEMENT  
Features  
Description  
The SC623 is a high efficiency charge pump LED driver  
using Semtech’s proprietary mAhXLifeTM technology.  
Performance is optimized for use in single-cell Li-ion  
battery applications.  
„
„
„
Input supply voltage range — 3.0V to 5.5V  
Charge pump modes — 1x, 1.5x and 2x  
Four programmable current sinks with 32 steps from  
0.5mA to 25mA  
„
Flash LED — 400mA max in flash mode, 250mA max  
continuous for spotlight  
Charge pump frequency — 250kHz  
The charge pump provides backlight current in  
conjunction with four matched current sinks. It also can  
supply continuous or bursted current to a flash LED using  
the dedicated flash driver current sink. The load and  
supply conditions determine whether the charge pump  
operates in 1x, 1.5x, or 2x mode. An optional fading  
feature that gradually adjusts the backlight current is  
provided to simplify control software. A flash-timeout  
feature disables the flash if active for longer than 1  
second.

„
SemWireTM single wire interface up to 75kbit/s  
Backlight current accuracy 1.5ꢀ typical  
Backlight current matching 0.5ꢀ typical  
Programmable fade-in/fade-out for main backlight  
External flash control pin to sync with camera  
Optional 1s flash time out  
Automatic sleep mode (LEDs o) IQ = 100μA  
Low shutdown current — 0.1μA (typical)  
Ultra-thin package — 3mm x 3mm x 0.6mm  
Fully WEEE and RoHS compliant  
The SC623 uses the proprietary SemWireTM single wire  
interface. The interface controls all functions of the device,  
including backlight and flash currents. The single wire  
implementation minimizes microcontroller and interface  
pin counts. The flash/spotlight output is triggered via  
either the SemWire interface or a dedicated pin.  
Applications  
„
„
Cellular phone backlighting and flash  
PDA backlighting and flash  
In sleep mode, the device reduces quiescent current to  
100μA while continuing to monitor the serial interface.  
Total current reduces to 0.1μA in shutdown.
