EMC CHARACTERISTICS (Cont’d)
True Open Drain Pin Protection
The centralized protection (4) is not involved in the
discharge of the ESD stresses applied to true
open drain pads due to the fact that a P-Buffer and
diode to VDD are not implemented. An additional
local protection between the pad and VSS (5a &
5b) is implemented to completely absorb the posi-
tive ESD discharge.
Multisupply Configuration
When several types of ground (VSS, VSSA, ...) and
power supply (VDD, VAREF, ...) are available for
any reason (better noise immunity...), the structure
shown in Figure 99 is implemented to protect the
device against ESD.
