ISO1042: ISO1042 question

Part Number: ISO1042

Hi Team,

May I ask which one I should look at for the current consumption of the primary and secondary sides of ISO1042BDWVR? What does BUS refer to? My VCC1 & VCC2 are both 5V inputs.  Thanks

    Hi Rock,

    Thanks for reaching out.

    As shown by the table below, there are two sets of possible supply voltage current consumption specifications that the device can have whenever VCC1 = 5V and VCC2 = 5V. Both sets of current consumptions specifications should be considered whenever you are using the device. However, for design purposes, we recommend that you pay close attention to the worst case current consumption specifications of the device, since it is common for systems to be designed around this. In the table referenced by your initial post, this happens whenever TXD = 0V. The worst case supply voltage current consumption specifications for VCC1 = 5V and VCC2 = 5V implementations are highlighted in the screenshot below.

    The "BUS" term refers to a CAN Bus, which is connected to the device by the CANH and CANL pins.
