Product Description
The WH4517V is a light to digital converter which combines an advanced ambient light sensor,an advanced proximity sensor and a high efficiency infra light VCSEL. The pitch ofsensor and VCSEL is only 2.1mm,so it is suitable for small IR hole design.
Ambient light sensor(ALS) built-in an optical filter for IR rejection, and providing a spectrum which is close to the human eye's response. ALS can work from dark to direct sunlight, the selectable detect range is about 40dB.ALS has excellent light ratio under different light conditions.
Proximity sensor(PS) built-in an 940nm optical filter for ambient light immunity, so PS can detect reflected IR light with high precision and excellent rejection.
WH4517V has programmable interupt function for ALS and PS with threshold based hysteresis.
