TPS55288: TPS55288RPMR

Part Number: TPS55288

Tool/software:

Hi Team, 

I want to figure out a question about TPS55288RPMR from my customer.

  • The rise time of SCL and SDA signal are both 120ns in TPS55288 datasheet as shown in first picture.

Question1: Under what frequency conditions is the rise time 120ns?

  • The I2C clock frequency of customer Master communication is 100K.

Question2: What is the required rise time for a 100khz signal?

Question3: The customer has measured a rise time of 281.2ns at 100kHz as shown in second picture. Is this result within normal parameters?

Thank you so much.

Best regards,

Thomas
