TSL2591

Datasheet - Apr. 2013 - ams163.5

The TSL2591 is a very-high sensitivity light-to-digital converter

that transforms light intensity into a digital signal output

capable of direct I

C interface. The device combines one

broadband photodiode (visible plus infrared) and one

infrared-responding photodiode on a single CMOS integrated

circuit. Two integrating ADCs convert the photodiode currents

into 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 TSL2591 supports a traditional level style

interrupt that remains asserted until the firmware clears it.

General Description

Figure TSL2591 – 2:

Block Diagram

The TSL2591 contains two integrating analog-to-digital

converters (ADC) that integrate currents from two photodiodes.

Integration of both channels occurs simultaneously. Upon

completion of the conversion cycle, the conversion result is

transferred to the Channel 0 and Channel 1 data registers,

respectively. The transfers are double-buffered to ensure that

the integrity of the data is maintained. After the transfer, the

device automatically begins the next integration cycle.

Communication with the device is accomplished through a

standard, two-wire I

C serial bus. Consequently, the TSL2591

can be easily connected to a microcontroller or embedded

controller. No external circuitry is required for signal

conditioning. Because the output of the device is digital, the

output is effectively immune to noise when compared to an

analog signal.

The TSL2591 also supports an interrupt feature that simplifies

and improves system efficiency by eliminating the need to poll

a sensor for a light intensity value. The primary purpose of the

interrupt function is to detect a meaningful change in light

intensity. The concept of a meaningful change can be defined

by the user both in terms of light intensity and time, or

persistence, of that change in intensity. The device has the

ability to define two sets of thresholds, both above and below

the current light level. An interrupt is generated when the value

of a conversion exceeds either of these limits. One set of

thresholds can be configured to trigger an interrupt only when

the ambient light exceeds them for a configurable amount of

time (persistence) while the other set can be configured to

trigger an immediate interrupt.

The ALS interrupt threshold registers provide the values to be

used as the high and low trigger points for the comparison

function for interrupt generation. If C0DATA crosses below the

low threshold specified, or above the higher threshold, an

interrupt is asserted on the interrupt pin.

If the C0DATA exceeds the persist thresholds (registers: 0x04 –

0x07) for the number of persist cycles configured in the PERSIST

the no-persist thresholds (registers: 0x08 – 0x0B) an interrupt

will be triggered immediately following the end of the current

integration.

Note that while the interrupt is observable in the STATUS

The Interrupt persistence filter sets the number of consecutive

out-of-range ALS cycles necessary to generate an interrupt.

Out-of-range is determined by comparing C0DATA (0x14 and

0x15) to the interrupt threshold registers (0x04 - 0x07). Note

that the no-persist ALS interrupt is not affected by the interrupt

persistence filter. Upon power up, the interrupt persistence

ALS data is stored as two 16-bit values; one for each channel.

When the lower byte of either channel is read, the upper byte

of the same channel is latched into a shadow register. The

shadow register ensures that both bytes are the result of the

same ALS integration cycle, even if additional integration cycles

occur between the lower byte and upper byte register readings.

Each channel independently operates the upper byte shadow

and CH1 data, it is recommended to read all four ADC bytes in

sequence. The simplest way to accomplish this is to perform a

four-byte I

protocol, which is set in the Command register TRANSACTION

Moisture Sensitivity

Optical characteristics of the device can be adversely affected

during the soldering process by the release and vaporization of

moisture that has been previously absorbed into the package.

To ensure the package contains the smallest amount of

absorbed moisture possible, each device is baked prior to being

dry packed for shipping.

Devices are dry packed in a sealed aluminized envelope called

a moisture-barrier bag with silica gel to protect them from

ambient moisture during shipping, handling, and storage

before use.

Shelf Life

The calculated shelf life of the device in an unopened moisture

barrier bag is 12 months from the date code on the bag when

stored under the following conditions:

• Shelf Life: 12 months

• Ambient Temperature: < 40°C

• Relative Humidity: < 90%

Rebaking of the devices will be required if the devices exceed

the 12 month shelf life or the Humidity Indicator Card shows

that the devices were exposed to conditions beyond the

allowable moisture region.

Floor Life

The FN package has been assigned a moisture sensitivity level

of MSL 3. As a result, the floor life of devices removed from the

moisture barrier bag is 168 hours from the time the bag was

opened, provided that the devices are stored under the

following conditions:

• Floor Life: 168 hours

• Ambient Temperature: < 30°C

•Relative Humidity: < 60%

If the floor life or the temperature/humidity conditions have

been exceeded, the devices must be rebaked prior to solder

reflow or dry packing.

Rebaking Instructions

When the shelf life or floor life limits have been exceeded,

rebake at 50°C for 12 hours.

Storage Information

TSL2591 – 24 Datasheet - Apr. 2013 - ams163.5

The term RoHS complaint means that ams products fully comply

with current RoHS directive. Our semiconductor products do

not contain any chemicals for all 6 substance categories,

including the requirement that lead not exceed 0.1% by weight

in homogeneous materials. Where designed to be soldered at

high temperatures, RoHS compliant products are suitable for

use in specified lead-free processes. ams Green means RoHS

compliant and no Sb/Br). ams defines Green that additionally

to RoHS compliance our products are free of Bromine (Br) and

Antimony (Sb) based flame retardants (Br or Sb do not exceed

0.1% by weight in homogeneous material).
