TCS3471 − Application Information: Hardware

Typical Hardware Application

A typical hardware application circuit is shown in Figure 34.

A 1-

μF low-ESR decoupling capacitor should be placed as close

as possible to the VDD pin.

Figure 34:

Typical Application Hardware Circuit

VBUS in Figure 34 refers to the I²C bus voltage, which is either

VDD or 1.8 V. Be sure to apply the specified I²C bus voltage shown

in the Available Options table for the specific device being used.

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-k

resistors. A 10-k

Ω pull-up resistor (RPI) can be used for the

interrupt line.
