8.2 Typical Application
The device integrates a 45k? pull-up resistor and series diode for responder node applications. For commander applications, an external 1k? pull-up resistor with series blocking diode can be used. Figure 8-1 shows the device being used in both commander mode and responder mode applications.
A. If RXD on MCU on LIN responder node has
internal pullup; no external pullup resistor is needed.
B. If RXD on MCU or LIN responder node does
not have an internal pullup requires external pullup resistor.
C. Commander node applications require and
external 1 kΩ pullup resistor and serial diode.
D. Decoupling capacitor values on
VSUP are system dependent but usually have 100nF, 1μF and ≥ 10μF.
