SIT1044T/3 Description

Short technical summary and product information.

The SIT1044T/3 is a high-performance CAN FD transceiver chip developed by SIT, designed for applications requiring communication between CAN protocol controllers and physical buses. It is suitable for use in vehicles such as trucks, buses, and cars, as well as industrial control systems.

Key features include a bus voltage tolerance of +/-40V, HBM ESD protection up to 8KV, and support for a 5Mbps flexible data rate (CAN FD). The chip meets or exceeds the ISO 11898 standard. It is available in SOP8 and DFN3*3-8 packages, offering small form factor options.

The SIT1044T/3 operates with I/O voltages supporting 3.3V and 5V MCUs. It includes features such as undervoltage protection on VCC and VIO power pins, driver (TXD) dominant timeout, standby bus (BUS) dominant timeout, and a low-power standby mode with wake-up capability. The device has undergone high and low temperature aging tests from -40°C to 125°C, making it suitable for industrial and automotive applications. It also boasts high electromagnetic interference immunity, ensuring that unpowered nodes do not interfere with the bus.

This transceiver is part of SIT's comprehensive series of CAN FD, CAN, and LIN transceiver models, positioning SIT as a domestic analog IC manufacturer with a full range of offerings for industrial and automotive sectors.
