TLIN2029-Q1: IBUS_LIM MIN Value

Daisuke Nomura
Intellectual 960 points
Part Number: TLIN2029-Q1

Tool/software:

I would like to know why a MIN value is specified in the IBUS_LIM specifications for the target part, TLIN2029.

I understand that the MAX value is a regulation of how much current can be flowed into the open collector output,

but I don't know intuitively how to think about the MIN value, so I would like an explanation. Please teach it.

    Hi Daisuke,

    This parameter defines current limitation for driver dominant state driver on VBUS = VBAT_max into ECU bus line. From ISO 17987-4, a transceiver shall be capable to sink at least 40 mA. The maximum current flowing into the node shall not exceed 200 mA under DC conditions to avoid possible damage.

    Regards,

    Sean
