General Description
Figure TSL2591 – 1:
Key Benefits and Features
The TSL2591 is a very-high sensitivity light-to-digital converter
that transforms light intensity into a digital signal output
capable of direct I2C 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.

Address field/special function field. Depending on the transaction
type, see above, this field either specifies a special function
command or selects the specific control-status-data register for
subsequent read and write transactions. The field values listed
below apply only to special function commands.

Reserved – Do not write
The interrupt set special function command sets the interrupt bits
in the status register (0x13). For the interrupt to be visible on the
INT pin, one of the interrupt enable bits in the enable register
(0x00) must be asserted.
The interrupt set special function must be cleared with an interrupt
clear special function. The ALS interrupt clear special functions
clear any pending interrupt(s) and are self-clearing.
