TLIN1029-Q1: Transition destination when Vsup > Vsup_under and EN=low in Operation State Diagram

F.N

Part Number: TLIN1029-Q1
Other Parts Discussed in Thread: TPIC1021A-Q1,

Hi team,

As to TPIC1021A-Q1, transition is made from unpowered system state to sleep mode
in the conditions of VSUP > VSUP_UNDER and EN = Low.

But as to TLIN1029-Q1, the transition is made from unpowered system state to standby mode.

Please see the figures below.

My customer wants to know the reason why the transition destination was changed.
Please let me know.

Best regards,

Nakano-san,

The switch was partially made to have a defined RXD state on power up instead of floating, and the stronger pull-up termination. This is also consistent with all of our newer LIN devices. In either case, holding EN high on power will put the device directly into Normal mode.

Please let me know if you have any other questions or concerns.

Regards,

I think that the customer wants to know whether there was a problem with the status control flow of
TPIC1021A-Q and changed.
