Part Number: TCAN1462-Q1

Hi Team, 

TCAN1462-Q1 can indicate the remote wake up request from CAN bus on RXD pin. 

When remote wake up request received, RXD will pull low to indicate as below screenshot. But what is the duration for RXD stay low to indicate remote wake up request? I don't find this info in datasheet. 

Thanks!

    Ethan,

    Thanks for asking! The RXD pin stays LOW as long as the bus remains dominant after tWK_FILTER. In the image above, the graphic is trying to show that RXD goes HIGH again once the bus returns to a recessive state. If hypothetically the bus had remained dominant, then RXD would have remained LOW until the bus returned to recessive.

    Best,

    Danny
