Hi Team,
TPS54550's datasheet says "Do not use external pull-up resistors".
But now customer is connecting another IC to SSENA pin and using pull-up resistor.
Sometimes SSENA will be "L" which cause TPS54550's stops work.
Maybe this phenomenon is caused by abnormal of IC connected to SSENA pin,
but is there any possibility that this phenomenon is caused by the pull-up resistor?
If yes, could you explain why this happens?
Thanks.
Regards,
Jo
