illustrate

“ LP5522 is a simple single-wire programmable LED controller in a 6-ball micro SMD package. It provides constant current through a high-side driver. The output current can be set from 1 mA to 20 mA with 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 The control uses only one signal. The signal controls the direct LED driver or initiates a previously programmed blinking sequence.

“ LP5522 Autonomous works without a clock signal from the master device. Very low LED driver headroom voltage makes it possible to use a supply voltage close to the forward voltage of the LED. Current consumption LP5522 When the LED is turned off, all supporting functions are also turned off once the controller is disabled. The very small micro SMD package with minimal external component count makes it ideal for handheld devices.
