3.3.2.1 Global Setting

When all the LED outputs are inactive, the LP50xx device is able to enter power-save mode automatically, thus lowering idle-current consumption down to 10 μA (typical). The automatic power-save mode is enabled when register bit Power_Save_EN = 1 (default) and all the LEDs are off for a duration of >30 ms. Almost all analog blocks are powered down in power-save mode. If any I²C command to the device occurs, the LP50xx device returns to the NORMAL mode. Set the Power Saver switch to activate the function (see Figure 8).
