LP5522 Programmable LED Driver June 2007 LP5522 Programmable LED Driver General Description The LP5522 is a simple single wire programmable LED controller 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. The LP5522 works autonomously without a clock signal from the master device. Very low LED driver...
