ADI LT1796IS8 125kbps Overvoltage Fault Protected CAN Transceiver

Shenzhen Mingjiada Electronics Co., Ltd., a well-known domestic supplier of electronic components, offers the ADI LT1796IS8 high-reliability CAN bus transceiver chip in stock. This chip is specifically designed for industrial and automotive electronic systems, featuring ±60V overvoltage protection, a data transfer rate of 125 kbps, and excellent EMI suppression capabilities, making it an ideal choice for building a stable and reliable CAN communication network.

LT1796IS8 Product Overview:

LT1796IS8 CAN transceiver provides built-in fault tolerance to survive in industrial and automotive environments. Discrete protection devices are not needed. Bus interface pins can withstand voltage faults up to ±60V with respect to ground with no damage to the device. Faults may occur while the transceiver is active, shut down or powered off. On-chip ESD protection withstands up to ±15kV air discharges and ±8kV contact mode discharges tested per IEC-1000-4-2. Loss of power or ground connections does not damage the IC.

LT1796IS8 operates with data rates up to 125kbaud. A slew control pin allows control of transmitted data pulse edges to control EMI and reflection problems on imperfectly terminated lines. High output current drive allows the use of inexpensive PVC cable with impedance as low as 72Ω. The 100kΩ input impedance allows up to 256 transceivers per data network.

Key features of the LT1796IS8 include:

Exceptional overvoltage protection capability: The bus interface pins can withstand voltage faults up to ±60V (relative to ground potential) without damaging the device, and this protection is effective whether the transceiver is in operation, shutdown, or power-off mode.

Robust ESD protection: The on-chip ESD protection circuit can withstand air discharge tests of up to ±15kV and contact mode discharge tests of up to ±8kV, fully meeting the IEC-1000-4-2 Level 4 specification requirements.

High reliability design: Loss of power or ground connections will not damage the IC, and all output pins provide short-circuit protection and thermal shutdown protection functions.

Flexible node expansion: A 100kΩ input impedance enables each data network to support up to 256 transceiver nodes, meeting the networking requirements of complex systems.

Optimised EMI performance: The data pulse edge of the transmitted data can be adjusted via the conversion rate control pin, effectively suppressing EMI and reflection issues on improperly terminated lines.
