2.3. Power domain separation and ESD protection
The epc901 chip has internally 5 different power domains and 3 ground references which are interconnected with ESD protection diodes.
All pins are also equipped with ESD protection diodes. Figure 5 shows this functional circuit. The diodes have a breakthrough voltage of
0.3V. The designer has to take care that none of these diodes become conductive either at power-up, power-down or normal operation.
