There is an internal pull-up resistor with a serial diode structure to VSUP, so no external pull-up components are required for the LIN responder node applications. An external pull-up resistor (1-kΩ) and a series diode to VSUP must be added when the device is used for commander node applications as per the LIN specification.
Figure 9-1 shows a commander node configuration and how the voltage levels are defined
