3.3.2 GUI Functions
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
μ
A (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 I
2
C 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 ).
