TMD3725 − Application Information

Schematic

Figure 58:

Typical Applications Circuit

Typical Applications Circuit: It is important to place the 4.7μF (VDD) and 10μF (LEDA) capacitors at the package

pins.

Note(s):

1. Place the 4.7μF and 10μF LEDA capacitors within 5mm of the module.

2. The value of the I²C pull up resistors RPU should be based on the 1.8V bus voltage, system bus speed and trace capacitance.

3. The bulk capacitor can affect the stability of a regulated supply output and should be chosen with the regulator characteristics in

mind.

4. VSS and PGND should be connected to the same solid ground plane as close to the device as possible.
