3 Description

The TCAN857-Q1 is a high speed controller area

network (CAN) transceiver that meets the physical

layer requirements of the ISO 11898-2:2024 highspeed

CAN specification. The transceiver is designed

for classical CAN and CAN FD networks up to 5

megabits per second (Mbps).

The transceiver supports two modes of operation;

normal mode and silent mode. The transceiver also

includes many protection and diagnostic features

including thermal shutdown (TSD), TXD-dominant

timeout (DTO), and bus fault protection up to ±40V.

The device has defined fail-safe behavior in supply

under-voltage or floating pin scenarios.

The transceiver features an integrated level shifter

on the VIO pin which supplies internal logic-level

translation for interfacing the transceiver I/Os directly

to 3.3V, or 5V logic level. These transceivers are

not only available in industry-standard SOIC-8 and

VSON-8 packages, but also have a space-saving

small footprint SOT-23 package option.
