TSL2591 – 18

Datasheet - Apr. 2013 - ams163.5

Figure TSL2591 - 17 shows a typical hardware application

circuit. A 1-μF low-ESR decoupling capacitor should be placed

as close as possible to the VDD pin. VBUS in this figure refers to

the I2C bus voltage, which is equal to VDD.

Figure TSL2591 – 17:

Typical Application Hardware Circuit

The I2C signals and the Interrupt are open-drain outputs and

require pull-up resistors. The pull-up resistor (RP) value is a

function of the I2C bus speed, the I2C 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.
