APPLICATIONS
Background
The Controller Area Network (CAN) is a serial
communication protocol designed for providing reliable
high speed data transmission in harsh environments. TVS
diodes provide a low cost solution to conducted and radiated
Electromagnetic Interference (EMI) and Electrostatic
Discharge (ESD) noise problems. The noise immunity level
and reliability of CAN transceivers can be easily increased
by adding external TVS diodes to prevent transient voltage
failures.
The NUP2105L provides a transient voltage suppression
solution for CAN data communication lines. The
NUP2105L is a dual bidirectional TVS device in a compact
SOT23 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 NUP2105L has been tested to EMI and ESD
levels that exceed the specifications of popular high speed
CAN networks.
CAN Physical Layer Requirements
Table 1 provides a summary of the system requirements
for a CAN transceiver. The ISO 118982 physical layer
specification forms the baseline for most CAN systems. The
transceiver requirements for the Honeywell
Smart
Distribution
Systems
(SDS
)
(AllenBradley) DeviceNet
high speed CAN networks
are similar to ISO 118982. The SDS and DeviceNet
transceiver requirements are similar to ISO 118982;
however, they include minor modifications required in an
industrial environment.
