Power supply sequence

ALL register of this IC is reset when VCC powers up. There are some notes about power up and down sequence as

shown below.

More than 2ms is needed to activate this IC after VCC becomes more than 2.3V from less than 0.4V.

More than 1ms (VCC < 0.4V) is needed before supplying power to this IC.

(Note1)

”Active” state is that this IC works and accept I

ALS Sensitivity Adjustment Function

This IC is capable of changing its ALS sensitivity. This is used to compensate the effect of attenuation by the optical

window. Adjustment is done by changing the measurement time. For example, when transmission rate of optical window

is 1/n (measurement result becomes 1/n times if optical window is set), the effect of optical window is compensated by

changing sensor sensitivity from default to n times.
