Isolated CAN Transceiver EVM
This User Guide details the design and operation of the evaluation module (EVM) for the ISO1050 isolated
CAN transceiver.
This Guide explains the user configurable I/O loads for the EVM configurations, and presents a typical lab
setup and typical output waveforms.
CAUTION
Please note that while these devices provide galvanic isolation of up to 4000 V,
this EVM cannot be used for isolation voltage testing. It is designed for the
evaluation of device operating parameters only and may be damaged if high
voltage (> 5.25 V) is applied anywhere in the circuit.
