When selecting a CAN transceiver like SIT1050, consider these key factors:
● Ensure system voltage matches (5V).
● Confirm communication speed requirements (up to 1 Mbps).
● Does the temperature range cover the application environment?
● Will the device face high EMI/EMC challenges?
● Need high ESD protection for industrial or automotive use?
● Require undervoltage lockout, thermal shutdown, or fail-safe features?
● Need compact layout? Choose DFN package for space-saving design.
