Product Overview: Texas Instruments ISO1050DUBRG4

The Texas Instruments ISO1050DUBRG4 is a robust, high-performance isolated CAN (Controller Area Network) transceiver that serves as a critical interface between CAN protocol controllers and the physical two-wire CAN bus. Designed to meet the demanding requirements of automotive and industrial communication systems, this device provides galvanic isolation, which enhances safety and system reliability by protecting the electronics from voltage spikes and ground loops.

Key Features

• Isolation: The ISO1050DUBRG4 incorporates Texas Instruments' proprietary silicon dioxide (SiO2) insulation barrier, providing 2500 Vrms of isolation for 1 minute per UL 1577. This feature ensures that the device can withstand harsh industrial environments and maintain signal integrity.
• Bus Fault Protection: The device can handle bus fault voltages ranging from -27V to +40V, thereby offering robust protection against transients and other voltage disturbances on the CAN bus lines.
• High-Speed Data Rates: It supports CAN data rates up to 1 Mbps, making it suitable for high-speed data transmission applications within the CAN network.
• Low Power Consumption: The ISO1050DUBRG4 is designed for low-power operation, which reduces power dissipation and improves efficiency in your system design.
• Extended Temperature Range: With an operational temperature range from -55°C to +105°C, the transceiver is capable of reliable performance in extreme temperature conditions, which is ideal for automotive and industrial applications.
• Package: The device comes in an 8-pin SOIC (DUB) package, which is compact and suitable for space-constrained applications.

Applications

The ISO1050DUBRG4 from Texas Instruments is a versatile component that can be used in a variety of applications, including:

• Industrial automation and control systems
• Automotive networks, such as body control modules and powertrain systems
