LM3880: About ESD

Expert 1810 points
Part Number: LM3880

Dears,

 I have a customer who used LM3880 encountering some ESD issues.

I was told that It works fine under normal condition. But the LM3880 tends to be a low level with interference, which causes CPU's reset, and the phenomenon can be seen with eyes, as well as unacceptable. we need pass the ESD in the 7kv on our product ground line with no reset phenomenon.Could you give some direction?

Best Regards,

Jenny

    Hi

    LM3880 has been followed ANSi/ESDA/JEDEC JS-001 for the ESD test(+/- 2KV). If their ESD requirement is much higher, a special ESD silicon may be considered to protect. You may find such devices at www.ti.com.
