LTR-559ALS-01
1. Description
2
The LTR-559ALS-01 is an integrated low voltage I C digital light sensor [ALS] and proximity sensor [PS] with built-in emitter,
in a single miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal
2
capable of direct I C interface. It provides a linear response over a wide dynamic range from 0.01 lux to 64k lux and is well
suited to applications under high ambient brightness. With built-in proximity sensor (emitter and detector), LTR-559ALS-01
offers the feature to detect object at a user configurable distance.
The sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves system
efficiency. The sensor also supports several features that help to minimize the occurrence of false triggering. This CMOS
design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability
to the end customers.

Notes:
1)
When reading ALS data registers, read sequence should always be from lower address to higher address (E.g. For ALS
data, Ch1 data should be read first followed by Ch0 data. Read sequence should be 0x88, 0x89, 0x8A, 0x8B. When 0x8B is
read, all four ALS data registers will be populated with new set of data).
2)
When setting of INTERRUPT register (addr 0x8F) is necessary, it should be done before the device is in Active mode.

ALS_CONTR Register (0x80)
The ALS_CONTR register controls the ALS Gain setting, ALS operation modes and software (SW) reset for the sensor.

The ALS sensor can be set to either standby mode or active mode. At either of these modes, the I C circuitry is always
active. The default mode after power up is standby mode. During standby mode, there is no ALS measurement performed
2
but I C communication is allowed to enable read/write to all the registers.

ALS_MEAS_RATE Register (0x85)
The ALS_MEAS_RATE register controls the integration time and timing of the periodic measurement of the ALS in active
mode. ALS Measurement Repeat Rate is the interval between ALS_DATA registers update. ALS Integration Time is the
measurement time for each ALS cycle.
ALS Measurement Repeat Rate must be set to be equal or larger than the ALS Integration Time. If ALS Measurement
Repeat Rate is set to be smaller than ALS Integration Time, it will automatically be reset to be equal to ALS Integration
Time by the IC internally.

ALS_DATA_CH1 Register (0x88 / 0x89) (Read Only)
The ALS_DATA registers should be read as a group, with the lower address read back first (i.e. read 0x88 first, then read
0x89). These two registers should also be read before reading channel-0 data (from registers 0x8A, 0x8B).

When the I C read operation starts, all four ALS data registers are locked until the I C read operation of register 0x8B is
completed. This will ensure that the data in the registers is from the same measurement even if an additional integration
cycle ends during the read operation. New measurement data is stored into temporary registers and the ALS_DATA
2
registers are updated as soon as there is no on-going I C read operation.
The ALS ADC channel-1 data is expressed as a 16-bit data spread over two registers. The ALS_DATA_CH1_0 and
ALS_DATA_CH1_1 registers provide the lower and upper byte respectively.

ALS_ PS_STATUS Register (0x8C) (Read Only)
The ALS_PS_STATUS register stores the information about ALS data status.
New data means data has not been read yet.
When the measurement is completed and data is written to the data register, the data status bit will be set to logic 1. When the
data register is read, the data status bit will be set to logic 0.
Interrupt status determines if the ALS interrupt criteria are met. It will check if the ALS measurement data is outside of the range
defined by the upper and lower threshold limits.
ALS Data Valid bit indicates the validity of the ALS data in Ch0 and Ch1.

PS_DATA_0 Register (0x8D / 0x8E) (Read Only)
The PS ADC channel data are expressed as a 11-bit data spread over two registers. The PS_DATA_0 and PS_DATA_1
2
registers provide the lower and upper byte respectively. When the I C read operation starts, both the registers are locked
2
until the I C read operation is completed.
This will ensure that the data in the registers is from the same measurement
even if an additional integration cycle ends during the read operation.
New measurement data is stored into temporary
2
registers and the PS_DATA registers are updated as soon as there is no on-going I C read operation.
PS Saturation Flag is used for monitoring the internal IC saturation. It will be flagged when the IC has reached saturation
and not able to perform any further PS measurement. The PS Saturation Indicator Enable bit in PS_CONTR Register
(0x81) has to be enabled in order to use this feature. If it is not enable, the flag will always be indicated as 0.

INTERRUTP Register (0x8F) (Read Only)
The INTERRUPT register controls the operation of the interrupt pin and functions. When the Interrupt Mode is set to 00,
the INT output pin 2 is inactive / disabled and will not trigger any interrupt. However at this condition, the
ALS_PS_STATUS register will still be updated.
Note that when this register is to be set with values other than its default values, it should be set before device is in Active
mode.

PS_THRES Register (0x90 / 0x91 / 0x92 / 0x93)
The PS_THRES_UP and PS_THRES_LOW registers determines the upper and lower limit of the interrupt threshold
value respectively. These two values form a range and the interrupt function compares if the measurement value in
PS_DATA registers is inside or outside the range. The interrupt function is active if the measurement data is outside the
range defined by the upper and lower limits. The data format for PS_THRES must be the same as PS_DATA registers.
These registers must be applied dynamically to have hysteresis interruption.

13. Moisture Proof Packaging
All LTR-559ALS-01 are shipped in moisture proof package. Once opened, moisture absorption begins. This part is
compliant to JEDEC J-STD-033A Level 3.
Time from Unsealing to Soldering
After removal from the moisture barrier bag, the parts should be stored at the recommended storage conditions and
soldered within seven days. When the moisture barrier bag is opened and the parts are exposed to the recommended
storage conditions for more than seven days, the parts must be baked before reflow to prevent damage to the parts.

Recommended Metal Stencil Aperture
It is recommended that the metal stencil used for solder paste printing has a thickness (t) of 0.11mm (0.004 inches / 4 mils)
or 0.127mm (0.005 inches / 5 mils).
The stencil aperture opening is recommended to be 0.72mm x 0.60mm which has the same dimension as the land
pattern. This is to ensure adequate printed solder paste volume and yet no shorting.
