Part Number: SN6505A
My customer will use SN6505A.
He is doing EMC test on his product and SN6505A seems stop switching when ESD test.
He understands this is not device matter and should optimize his board design, but could you please provide any comment on following question?
Hi Shota Mago,
Thank you for posting to E2E! How is the EMC / ESD test conducted? How is the ESD strike connected to the circuit?
It will be helpful if you can share a schematic demonstrating the test setup and connections along with Vcc, D1/D2, and EN oscilloscope waveforms during the test. If it’s best to share this privately, please feel free to send me a Request to Connect and Personal Message.
Please also let us know how long the SN6505A stops switching during this test and whether it recovers without requiring a power cycle.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Manuel Chavez:
Hi Shota-san,As discussed over email, our customer found the SN6505A would not turn off during the ESD test when EN was shorted to Vcc directly instead of through a 4.99kΩ resistor.Our systems and design teams confirmed a pull-up resistor from EN to Vcc is not required for SN6505. Please notify our customer that it is okay to short EN to Vcc.Thank you,Manuel Chavez
