PRODUCTION DATA.
The 5.6-V Zener diodes used to protect the communication pins of the gas gauge from ESD should be located as close as possible to the pack connector. The grounded end of these Zener diodes should be returned to the Pack(–) node rather than to the low-current digital ground system. This way, ESD is diverted away from the sensitive electronics as much as possible.
