Datasheet  
Constant Current LED Driver  
with 64 Dimming Steps for up to 4 LEDs  
BD1754HFN  
General Description  
Key Specification  
The multi-level brightness control LED works as a  
constant current driver in 64 steps, so that the driving  
current can be adjusted finely. BD1754HFN is best  
suited to turn on LEDs that require high-accuracy LED  
brightness control.  
Operating power supply voltage range: 2.7V to 5.5V  
Quiescent Current:  
0.1μA (Typ.)  
Operating temperature range:  
-30°C to +85°C  
Package W(Typ.) x D(Typ.) x H(Max.)  
Features  
Current regulation for LED up to 4 parallels  
Adjustable constant current 64 steps  
High accuracy and matching of each current  
channel (0.5% Typ.)  
Brightness control via a single-line digital control  
interface (Uni-Port Interface Control = UPIC)  
Applications  
This driver can be used in various fields such as  
HSON8  
2.90mm x 3.00mm x 0.60mm  
mobile phones, portable game machines and etc.
