Measurement modes
Mode
Description
OFF
The device is inactive. Other units may use the I2C bus without any restrictions; I/O
pins and INT are in high Z state. There is no sink current through the LED
STAND-BY
This is the initial mode after power-up. IDD is typ. 0.8A. No measurement is
performed. Device can be activated by I2C bus communication. Data registers can
be read and written.
ALS / PS free -
RUNNING
Measurements are triggered internally by the SFH 7776. Stand-by / active mode for
ALS and PS, measurement times, interrupt options and LED current can be adjusted
via I²C register. Measurement results can be read from the data register, the status
from the interrupt register.

If VDD exceeds the threshold voltage, the sensor will switch from OFF mode to STAND-BY mode. As
shown in the transition-diagram above it is possible to switch between all modes without any restriction.
