The TJA1044T/1 is a high-speed CAN bus transceiver from NXP Semiconductors’ Mantis family. It provides a physical-layer interface between a CAN protocol controller and a two-wire CAN bus, enabling reliable differential signal transmission and reception.
This device supports Classical CAN data rates up to 1Mbps and complies with the ISO 11898-2 standard. Designed for 12V automotive electronic systems, it features a low-current standby mode with remote wake-up capability via the CAN bus, helping reduce overall system power consumption.
The TJA1044T/1 offers excellent electromagnetic compatibility (EMC) and electrostatic discharge protection. Integrated protection features include TXD dominant time-out, undervoltage detection, and thermal shutdown, improving communication reliability in automotive environments.
Housed in an 8-pin SO8 surface-mount package, the device operates with a supply voltage of 4.5V to 5.5V and supports a junction temperature range of -40°C to +150°C. It is AEC-Q100 qualified and suitable for automotive body control modules, instrument clusters, in-vehicle networks, and other CAN communication systems.
