LP5522  
Programmable LED Driver  
General Description  
The LP5522 is a simple single wire programmable LED con-  
troller in six bump micro SMD package. It provides constant  
current flow through high side driver. Output current can be  
set from 1 mA to 20 mA by using an external resistor on the  
ISET pin. If no external resistor is used, output current is set  
to 5 mA default current. The LP5522 is controlled using only  
one signal. The signal controls either directly the LED driver  
or it launches previously programmed blinking sequence.  
Features  
Programmable blinking sequence  
1 to 3 programmable pulses  
1 ms to 255 ms LED on time  
10 ms to 2500 ms LED off time  
Single or continuous run of programmed blinking  
sequence  
Constant current high side output driver  
Adjustable current with external resistor  
0.2 uA typical shutdown current  
The LP5522 works autonomously without a clock signal from  
the master device. Very low LED driver headroom voltage  
makes possible to use supply voltages close to LED forward  
voltage. Current consumption of the LP5522 is minimized  
when LED is turned off and once controller is disabled all  
supporting functions are also shut down. Very small micro  
SMD package together with minimum number of external  
components is a best fit for handheld devices.  
Autonomous operation without external clock  
Micro SMD-6 package with 0.4 mm pitch:  
1.215 mm x 0.815 mm x 0.6 mm (LxWxH)  
Applications  
Indicator lights  
Phone cosmetics  
Toys
