TSL2591 Datasheet - Apr. 2013 - ams163.5 General Description The TSL2591 is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct I 2C 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.

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 2C 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.

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 register an interrupt will be triggered. If the C0DATA exceeds 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 register (0x13), it is visible only on the INT pin when AIEN or NPIEN are enabled in the ENABLE register (0x00). Upon power up, the interrupt threshold registers default to 0x00.

Datasheet - Apr. 2013 - ams163.5 ALS Data Register (0x14 - 0x17) 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 register. So to minimize the potential for skew between CH0 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 I2C read operation using the auto-increment protocol, which is set in the Command register TRANSACTION field.

A 1-μF low-ESR decoupling capacitor should be placed as close as possible to the VDD pin. V BUS in this figure refers to the I2C bus voltage, which is equal to V DD. Figure TSL2591 – 17: Typical Application Hardware Circuit TSL2591 The I 2C signals and the Interrupt are open-drain outputs and require pull-up resistors. The pull-up resistor (RP) value is a function of the I2 C bus speed, the I 2C bus voltage, and the capacitive load. The ams EVM running at 400 kbps, uses 1.5-kΩ resistors. A 10-kΩ pull-up resistor (RPI) can be used for the interrupt line.

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.
