Product details

Automotive CAN transceiver that handles 28V supply and 150°C junction

It supports CAN FD data rates up to 5 Mbps and operates from a 4.5V to 28V supply, covering both 12V passenger car and 24V commercial vehicle rails without external pre-regulation. The 14-VDFN package with wettable flank allows AOI inspection after reflow, a requirement for zero-defect automotive production lines.

135 mV hysteresis and single-channel topology

The receiver hysteresis of 135 mV provides noise margin on the differential CAN bus, reducing false bit detection in electrically noisy environments like motor drives or alternator proximity. The single driver/receiver pair (1/1) is the standard node topology for a CAN FD endpoint; no redundant bus interface is present.

With a supply range from 4.5V to 28V, this transceiver handles load-dump transients common in automotive 12V and 24V systems without external clamping.

No last-time-buy or obsolescence risk is indicated for this order code.
