TCAN4550-Q1: For under voltage lockout table

Part Number: TCAN4550-Q1

Hi team,

A customer asks some questions about TCAN4550-Q1.

The table has no state for (Vsup > UVsup), (VIO < UVIO) and (VCCOUT < UVCCOUT). So, can you answer the followings?

1. For below condtion, what is the mode? Sleep mode or other mode?

          Vsup > UVSUP

          VIO < UVIO

          RST pin is Low

2. For above mode, what is the bus state? High impedance or not?

Thank,

Sam Lee

    Hi Sam,

    Thanks for bringing this question to our attention.

    1. The device will be in Sleep mode if VSUP is supplied but VIO hits the undervoltage threshold for longer than tUV.
    2. It will be high impedance due to the device being in sleep mode.

    Please let me know if you have any other questions.

    Regards,
