TSL45315CL

The TSL45315CL is a digital ambient light sensor (ALS) from ams-OSRAM designed to approximate human eye response across diverse lighting conditions. It provides a direct 16-bit lux output through an I2C bus interface, simplifying integration into various systems.

Key features include three user-selectable integration times (100 ms, 200 ms, and 400 ms), allowing for flexibility in different lighting scenarios. The sensor boasts a wide dynamic range, spanning from 3 lux to 220,000 lux, making it suitable for applications exposed to direct sunlight. It also rejects 50 Hz/60 Hz lighting ripple, ensuring accurate readings in environments with artificial lighting.

The TSL45315CL operates with a 2.5-V supply voltage and a 1.8-V logic interface. Its low active current consumption of 110 μA typical, with a power-down mode drawing only 2.2 μA typical, enables the development of green products and extends battery life.

Applications for the TSL45315CL include outdoor lighting control for street lights and security systems, display backlight control for automotive instrumentation, cell phones, tablets, and notebooks, as well as solid-state and general lighting for daylight harvesting to maximize energy conservation.
