Description  
The TSL2562 and TSL2563 are low-voltage light-to-digital converters that transform light intensity to a digital  
2
signal output capable of direct I C (TSL2563) or SMBus (TSL2562) 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  
TSL2562 device permits an SMB-Alert style interrupt, and the TSL2563 device supports a traditional level style  
interrupt that remains asserted until the firmware clears it.  
While useful for general purpose light sensing applications, the TSL2562/63 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 TSL2562/63 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.
