詳細說明
The ISO1050DW by Texas Instruments sets a new standard in high-performance, galvanically isolated CAN communication. Its robust design and reinforced isolation barrier capable of withstanding up to 5 kVrms make it an ideal choice for industrial applications where reliability and safety are paramount. The transceiver supports both CAN 2.0A and CAN 2.0B protocols, ensuring compatibility with a wide range of CAN systems. Operating efficiently within a supply voltage range of 4.5V to 5.5V, the ISO1050DW incorporates thermal shutdown and short-circuit protection mechanisms for enhanced system reliability. With a high-speed data rate of up to 1 Mbps and a high transient immunity of ±50 kV/μs, this device delivers rapid and robust communication in electrically noisy environments. Packaged in a space-saving SOIC-8 format, the ISO1050DW is RoHS compliant and operates effectively across an industrial temperature range of -40°C to +105°C

常見問題解答
What is ISO1050DW?
The ISO1050DW is a high-performance, galvanically isolated dual-channel transceiver designed by Texas Instruments. It provides isolated bidirectional communication between two systems while ensuring high data integrity and safety in applications such as industrial automation, motor control, and automotive systems.
How Does ISO1050DW Work?
The ISO1050DW operates by using electromagnetic isolation techniques to transmit data signals across a barrier, typically a high-voltage isolation barrier. It features differential signaling to enhance noise immunity and data integrity. The transceiver enables communication between systems that operate at different ground potentials, providing protection against voltage transients and ground loops.
How Many Pins does ISO1050DW have and What are the Functions of the Pinout Configuration?
The ISO1050DW is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VCC1, GND1: Power supply and ground pins for channel 1.
- TX1, RX1: Transmitter and receiver pins for channel 1.
- VCC2, GND2: Power supply and ground pins for channel 2.
- TX2, RX2: Transmitter and receiver pins for channel 2.
- EN, RE, DE: Enable, receiver enable, and driver enable control pins.
What are the Pros and Cons of ISO1050DW?
Pros:
- Galvanic Isolation: Provides high-level isolation for enhanced safety and noise immunity.
- High Data Integrity: Ensures reliable data transmission in noisy industrial environments.
- Dual-Channel Design: Allows bidirectional communication between two systems.
- Wide Operating Voltage: Supports a wide range of voltage levels for flexible system integration.
- Robust Protection: Protects against voltage transients and ground potential differences.
Cons:
- Cost: Galvanically isolated components may be more expensive compared to non-isolated alternatives.
- Complexity: Requires careful consideration of isolation barriers and system grounding for proper functionality.
- Space Considerations: The 16-pin SOIC package may require more board space compared to smaller package options.
Are There Any Equivalents/Alternatives to ISO1050DW for Recommendation?
- The ISO1176T from Texas Instruments is another galvanically isolated transceiver option.
- Alternatives to the ISO1050DW include the ADuM1201 from Analog Devices and the Si823x series from Silicon Labs.
