Part Number: TCAN1043A-Q1

Tool/software:

Hi team

My customer wanted to enter into sleep mode from standby via an SWE timer timeout(>t_inactive) where Vcc>UVcc, Vio>UVio, Vsup>UVsup. 

Would you help provide the status in below listed items between B and C?

Wakerq flag, driver, receiver, RXD, IHM, nFault 

Thanks

    Hi Ted,

    This is not a recommended way to enter sleep mode during normal operation. SWE timer is usually 3-4 minutes long which is designed to reduce the current consumption when there is software error and the transceiver is stuck in standby mode or during the initial power up. A more preferred way to enter sleep mode from standby mode is using NSTB and EN pins.

    There are no pin status "between" two modes, the datasheet has listed the pin status in different modes, as that state diagram shows, or you can find in table 8-4.

    Regards,

    Sean
