Figure 9-8. System Present Pull-Down Resistor

Because the System Present signal is part of the pack connector interface to the outside world, it must be

protected from external electrostatic discharge events. The PRES pin has integrated ESD protection to 2 kV.

External protection can be added to support higher ESD protection requirements. The TPD1E10B06 single-

channel ESD protection diode (U2) can protect the input up to 30 kV, and the R8 reduces the holding current to

release the internal SCR in the event that it triggers.

9.2.2.2.4 SMBus Communication

The SMBus clock and data pins have integrated high-voltage ESD protection circuits; however, adding

TPD1E10B06 ESD protection diodes (U4 and U5) and series resistors (R24 and R25) provides more robust

ESD performance.
