The INH function of TJA1043T

[chenyu1]

Our client needs to use the INH function of TJA1043T. Theoretically, when CAN is in sleep mode, the INH pin is in float state. When the chip detects the start frame on the CAN bus, the INH will be raised. I would like to ask you the following two questions. Thank you!

Question 1:

Is the level of the INH pin always high when the INH is pulled high? Or just pull it up for a period of time, what is that period of time?

Question 2:

Does the TJA1043T have any power timing requirements for VCC and VIO?

Thank you Guowei. In addition, how long will it take for the INH to rise after receiving the external CAN wake-up signal?
