Chip Ambient Light Sensor, RoHS Compliant (PT-3528)
Chip Ambient Light Sensor IC type for security lighting with near human Eye photopic response.
Chip ambient light sensors (ALS) will also be known as photodetector, illumination sensors, photo transistor, brightness sensors, optical sensors, or simply light sensors. The ALS signal may be used to instruct the keypad LED driver to reduce keypad backlighting minimizing as much as 30% from the power within the input standby power mode. Inside a mobile phone, the ALS enables automatic charge of display backlight brightness over an array of illumination conditions from the dark atmosphere to sunlight. This control significantly improves visibility and minimizes power consumption since LCD backlighting is able to take around 51% through the power within the input standby mode.
The (PT-IC-AC-3528-520) is a high-precision environment-friendly ambient light sensor. Optical IC with spectral response close to human eye sensitivity. A single chip on the photosensitive surface of the built-in current amplifier circuit is able to measure the visible light band. Compared with traditional visible light to near-infrared receiving silicon products, the light IC has a smaller output fluctuation. Parameters can be directly substituted for the most versatile Cds resistor, so this sensor can be used as an environmentally friendly substitute for cadmium sulfide resistor.
The (PT-IC-BC-3528-550) using high quality chip packaging and processing super-plated infrared filter membrane on chip surface, so this sensor can fully filter infrared interference. It is no need to add the casing and extra filter and effective filtering out the effect of light reflection due to infrared emission on security products. This chip IC features high precision and excellent consistency, high temperature performance, working in high temperature environment, and dark current stability.
