TSL2591 – 18 Datasheet - Apr. 2013 - ams163.5
Figure TSL2591 - 17 shows a typical hardware application
circuit. A 1-F low-ESR decoupling capacitor should be placed
as close as possible to the V
DD
pin. V
BUS
in this figure refers to
the I
2
C bus voltage, which is equal to V
DD
.
Figure TSL2591 – 17:
Typical Application Hardware Circuit
The I
2
C signals and the Interrupt are open-drain outputs and
require pull-up resistors. The pull-up resistor (RP) value is a
function of the I
2
C bus speed, the I
2
C bus voltage, and the
capacitive load. The ams EVM running at 400 kbps, uses 1.5-k
resistors. A 10-k pull-up resistor (RPI) can be used for the
interrupt line.
