The LTM®2889 is a complete galvanically-isolated Controller Area Network (CAN) μModule® (micromodule)
transceiver. No external components are required – a
single supplypowersbothsidesofthe interface throughan
integrated, isolatedDC/DCconverter. Separateversionsare
available for 3.3V and 5V power supplies. The dual voltage
CAN transceiver and the adjustable regulator allow 3.3V
or 5V isolated power with either the 3.3V or 5V version.
Coupled inductors and an isolation power transformer
provide 2500VRMS ofisolationbetweenthe line transceiver
and the logic interface. This device is ideal for systems
wherethegroundloopisbroken, allowingforlargecommon
mode voltage ranges. Communication remains uninterrupted for commonmode transients greaterthan 30kV/μs.
Supports up to 4Mbps CAN with Flexible Data Rate
(CAN FD). A logic supply pin allows easy interfacing with
different logic levels from 1.62V to 5.5V, independent of
the main supply.
Enhanced ESD protection allows this part to withstand up
to ±25kV Human Body Model (HBM) on the transceiver
interface pins and ±10kV HBM across the isolation barrier
without latchup or damage.
