Dear, All
A customer is thinking the capacitor of a power supply is made bigger for a noise countermeasure.
Therefore a rise of a power supply becomes slow.
This power supply is being used for VCC of SN65HVDA1040A-Q1.
VCC of SN65HVDA1040A-Q1 has UVLO.
* Does this UVLO have a hysteresis?
It's considered that noise takes the time of rising of a power supply.
When not having a hysteresis in UVLO, I want you to answer below.
* When noise takes it around the threshold of ULVO, please tell me the voltage and time of the noise which can be permitted.
Thanks, Masami M.
