TLV493D returns NCK

Hi,

I'm using a TLV493D with a power separated by FET from microcontroller power, like Slave #1 in figure 14 of I2C interface note (https://www.infineon.com/dgdl/Infine...530e81c9db058c)

Sometimes my few TLVs return NCK and cannot recover even turn on/off by IO_0 pin.
A difference between the note and my project is SCL pin is high during 200us of after power on by getting IO_0 high.

Does this SCL behavior seriously affect the I2C address setting/communication?

I'm feeling strange since many of my TLVs are successfully work but this happens with few chips beside low frequency.
