EVALUATION KIT AVAILABLE MAX14878–MAX14880 2.75kV and 5kV Isolated CAN Transceivers General Description The MAX14878–MAX14880 family of high-speed
transceivers improve communication and safety by
integrating galvanic isolation between the CAN protocol
controller side of the device and the physical wires of the
network (CAN) bus. Isolation improves communication by
breaking ground loops and reduces noise where there are
large differences in ground potential between ports. The
MAX14879 provides up to 2750VRMS (60s) of galvanic
isolation, while the MAX14878/MAX14880 provide up to
5000VRMS (60s) of galvanic isolation.
All transceivers operate up to the maximum high-speed
CAN data rate of 1Mbps. The MAX14879/MAX14880
feature an integrated standby input (STB) on the isolated
side of the transceiver to disable the driver and place the
transceiver in a low-power standby mode. The MAX14878
does not include the standby input.
The MAX14878–MAX14880 transceivers feature integrated
protection for robust communication. The receiver input
common-mode range is ±25V, exceeding the ISO 11898
specification of -2V to +7V, and are fault tolerant up to
±54V. Driver outputs/receiver inputs are also protected
from ±15kV electrostatic discharge (ESD) to GNDB on the
bus side, as specified by the Human Body Model (HBM). …
