TLIN1022-Q1: TLIN1022-Q1 Lin Bus Capacitor

Hi

I want to know the Lin Bus Capacitor value specification.

1. What is the minimum and maximum value of the Lin Bus capacitor in the red rectangle?


2. Customer uses 1nF for LIN Bus Line. Is there any problem using 1nF?

    Cho,

    These values are set by the LIN standard, and depend on the configuration of the node. For slave nodes, the maximum amount of capacitance on the LIN pin allowed is 250pF, with the typical being 220pF; for master nodes there is no maximum, and the typical is 220pF. The overall amount of allowed capacitance on the LIN bus in a LIN cluster is maximum 10nF, minimum 1nF, typical 4nF. This value also has to take in to consideration the capacitance of the LIN pin on the transceiver itself.

    Please let me know if you have any other questions.

    Regards,
