tja1043 wake up

[zhouqichen]

hello,TJA1043T assumes that VBAT 24V, how much voltage is needed for the wake pin to wake up the CAN, and what connection method is available to make the wake wake up when connected to 9V

[TomasVaverka]

Hello,

A local wake-up event is triggered by a LOW-to-HIGH or HIGH-to-LOW transition on the WAKE pin since it has a bi-directional input threshold (falling or rising edge). The threshold voltage is specified in the datasheet, Table 8:

For more information, please take a closer look at the AH1014, Chapter 6.4 (Wake via pin WAKE).

Best regards,

Tomas
