ISOW7840DWER  

Digital Isolators

The ISOW7840DWER is a high-performance, low-power, dual-channel isolator from Texas Instruments. It is designed to provide reliable isolation between digital circuits in high-voltage and high-current applications.

Description:

The ISOW7840DWER is a monolithic integrated circuit that provides two independent digital isolators in a single package. It uses a capacitive coupling technique to provide isolation between the input and output sides of the device. The device has a low propagation delay and a high data transfer rate, making it suitable for high-speed data communication.

Features:

• Dual-channel isolator with independent channels for increased system reliability
• Low propagation delay of 5 ns (typical) for high-speed data communication
• High data transfer rate of up to 50 Mbps
• Low power consumption of 2.5 mA (typical) for each channel
• Wide input voltage range of 3.75 V to 5.5 V
• Wide operating temperature range of -40°C to 125°C
• Small package size of 6.25 mm x 6.25 mm

Applications:

The ISOW7840DWER is suitable for a wide range of applications that require high-speed, reliable, and isolated digital communication. Some of the key applications include:

1. Industrial control systems: The isolator can be used to isolate digital signals in industrial control systems, such as motor control, sensor interfaces, and data acquisition systems.
2. Medical equipment: The isolator can be used to provide isolation between the patient and the medical equipment, ensuring patient safety and equipment reliability.
3. Automotive systems: The isolator can be used in automotive systems, such as battery management systems, engine control units, and safety systems, to provide isolation between high-voltage and low-voltage circuits.
4. Power electronics: The isolator can be used in power electronics applications, such as solar inverters, motor drives, and power supplies, to provide isolation between the primary and secondary sides of the system.
5. Data communication: The isolator can be used in data communication applications, such as Ethernet and RS-485 interfaces, to provide isolation between the transmitter and receiver circuits.

In summary, the ISOW7840DWER is a high-performance, low-power, dual-channel isolator that provides reliable isolation between digital circuits in a wide range of applications. Its key features include low propagation delay, high data transfer rate, low power consumption, and a small package size.
