SLM770A Module Hardware Design Manual
MeiG Smart Technology Co., Ltd 77/77
Test item
Test condition
3, module other interfaces, ESD meet:
① Contact discharge should pass the test grade of ±0.5KV
② Air discharge should pass the test grade of ±1KV
6.5 ESD Features
SLM770A module design has considered the ESD problem, and do the ESD protection, but consider
SLM770A module in the transport and secondary development may also have ESD problem occurred,
so developers to view the protection of the final product ESD problem, besides must consider the
antistatic packaging processing. Please refer to the document interface design when the customer
application recommended circuit.
Refer to the following table for the ESD allowed discharge range for SLM770A module.
