TSL25413M

TSL25413M is an ALS, light-to-digital sensor. It is a very high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct I²C interface. The ALS sensor features 2 output channels, a visible channel, and an IR channel. The visible channel has a photodiode with a UV and IR blocking filter whereas the IR channel has a photodiode with an IR pass filter. Each channel has a dedicated data converter producing a 16-bit output. This architecture allows applications to accurately measure ambient light which enables devices to calculate illuminance to control a display backlight. The application includes ambient light sensing, and display backlight control.
