10.2 Typical Application
The device comes with an integrated 45 kΩ pull-up resistor and series diode for responder node applications. For commander node applications, an external 1 kΩ pull-up resistor with series blocking diode can be used. Typical LIN Bus shows the device being used in both commander and responder applications.
