The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.
The equipment must generally withstand both positive and negative discharges of at least 15 kV to all connector pins as well as to the case of the battery pack. Most require-ments go further than just requiring survival, insisting that there be no observable disruption in performance.
