TMD2621 − Application Information

Schematic

Figure 63:

TMD2621 Typical Application Circuit

Note(s):

1. Place VDD18 filter (R1, C1, C2) and VDD3 filter (C5) as close as possible to the module.

2. The value of the I²C pull up resistors (R6, R7) should be based on the bus voltage, system bus speed and trace capacitance.

3. R1, C1, C2, C5 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 XRES to a host GPIO pin to allow the device reset.
