3 Description

The TCAN844-Q1 is a high speed controller area

network (CAN) transceiver that is compatible with

physical layer requirements of the ISO 11898-2:2024

high-speed CAN specification.

The device includes internal logic level translation via

the VIO pin to allow for interfacing the transceiver I/O

directly to 3.3V, or 5V logic levels. The transceiver

supports a low-power standby mode and wake over

CAN which is compatible to the ISO 11898-2:2024

defined wake-up pattern (WUP).

The transceivers also include thermal-shutdown

TSD), TXD-dominant time-out (DTO), supply

undervoltage detection, and ±40V bus fault protection.

The devices have defined fail-safe behavior in

supply undervoltage or floating pin scenarios. These

transceivers are not only available in industrystandard

SOIC-8 and VSON-8 packages, but also

have a space-saving small footprint SOT-23 package

option.
