Digital Isolators

The ISO7321FCQDRQ1 is a high-performance, single-channel, digital isolator manufactured by Texas Instruments. It is designed to provide reliable and efficient isolation between digital circuits in various applications, such as industrial control systems, medical equipment, and power supplies.

Description:

The ISO7321FCQDRQ1 is a monolithic digital isolator that uses capacitive coupling to provide isolation between its input and output sides. It features a small, 6-pin, 1.6mm x 1.6mm QFN package, making it suitable for space-constrained applications.

Features:

1. Single-channel digital isolator
2. Capacitive coupling for isolation
3. Small 6-pin, 1.6mm x 1.6mm QFN package
4. Wide operating temperature range: -40°C to +125°C
5. Low power consumption: 2.5mA typical (3.3V supply)
6. High isolation voltage: 2.5kVRMS minimum
7. Fast propagation delay: 60ns typical (3.3V supply)
8. Low input and output voltage levels compatible with most digital circuits
9. Immune to electromagnetic interference (EMI) and radio frequency interference (RFI)
10. Available in a qualified package for automotive and industrial applications

Applications:

1. Industrial control systems: To provide isolation between control circuits and high-voltage power circuits.
2. Medical equipment: To isolate low-voltage control signals from high-voltage medical power supplies.
3. Power supplies: To isolate digital control signals from the main power circuit.
4. Data communication: To provide isolation in serial communication interfaces, such as RS-485 or SPI.
5. Automotive systems: To isolate digital signals in high-voltage battery management systems and electric vehicle powertrains.
6. Renewable energy systems: To provide isolation in solar power inverters and wind turbine control systems.
7. Test and measurement equipment: To isolate digital signals in high-voltage test equipment.

The ISO7321FCQDRQ1 is a versatile and reliable digital isolator that can be used in a wide range of applications where isolation between digital circuits is required. Its small size, low power consumption, and high isolation voltage make it an ideal choice for space-constrained and high-reliability applications.
