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 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.
