6.6 ESD Characteristics
SLM750 is a consumer terminal product. Although we have considered possible problems of
ESD and took some protections, considering problems in the transport and secondary development,
we need to consider the protection of final product ESD, including the anti electrostatic packaging
processing. You can refer to the recommended circuit of interface design in the document when
using in applications.
The following table shows the discharge range of SLM750 ESD:

Tes t point Contact discharge Air discharge Unit
VBAT, GND ±5 ±10 KV
Antenna interfaces ±4 ±8 KV
Other interfaces ±0.5 ±1 KV
