illustrate

“ LP5522 is a simple single-wire programmable LED controller in a 6-ball micro SMD package. It provides a constant current through a high-side driver. The output current can be set from 1 mA to 20 mA via an external resistor on the ISET pin. If no external resistor is used, the output current is set to the default current of 5 mA. “ LP5522 Control uses only one signal. The signal controls the direct LED driver or initiates a previously programmed flashing sequence.

“ LP5522 Autonomous works do not have clock signals from the main device. Very low LED driver headroom is possible using a supply voltage close to the forward voltage of the LED. Current consumption LP5522 When the LED is off, all companion functions are also turned off once the controller is disabled to minimize. The very small micro SMD package with minimal number of external components makes it ideal for use in handheld devices.
