Description

The TSL2568 and TSL2569 are high-sensitivity light-to-digital converters that transform light intensity to a digital

signal output capable of direct I C (TSL2569) or SMBus (TSL2568) interface. Each device combines one

broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS

integrated circuit capable of providing a near-photopic response over an effective 20-bit dynamic range (16-bit

resolution). Two integrating ADCs convert the photodiode currents to a digital output that represents the

irradiance measured on each channel. This digital output can be input to a microprocessor where illuminance

(ambient light level) in lux is derived using an empirical formula to approximate the human eye response. The

TSL2568 device permits an SMB-Alert style interrupt, and the TSL2569 device supports a traditional level style

interrupt that remains asserted until the firmware clears it.

While useful for general purpose light sensing applications, the TSL2568/69 devices are designed particularly

for display panels (LCD, OLED, etc.) with the purpose of extending battery life and providing optimum viewing

in diverse lighting conditions. Display panel backlighting, which can account for up to 30 to 40 percent of total

platform power, can be automatically managed. Both devices are also ideal for controlling keyboard illumination

based upon ambient lighting conditions. Illuminance information can further be used to manage exposure

control in digital cameras. The TSL2568/69 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel

televisions, cell phones, and digital cameras. In addition, other applications include street light control, security

lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.
