TMD2635 − Application Information

Figure 48:

Schematic

Note(s):

1. Place the C1 and C2 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. C1 and C2 are critical components to protect the device during high voltage ESD strikes.

4. In systems subjected to high voltage ESD strikes, it is recommended to connect VDD to a host GPIO pin to allow the device to be

independently power cycled.
