APPLICATIONS SECTION

The NUP1105L provides a transient voltage suppression

solution for the LIN data communication bus. The

NUP1105L is a dual bidirectional TVS device in a compact

SOT−23 package. This device is based on Zener technology

that optimizes the active area of a PN junction to provide

robust protection against transient EMI surge voltage and

ESD. The NUP1105L has been tested to EMI and ESD

levels that exceed the specifications of popular high speed

LIN networks.

The NUP1105L device can be used to provide transcient

voltage suppression for a single data line CAN system.

Figure 7 provides an example of a single data line CAN

protection circuit.
