ISO7762FQDBQRQ1 5 kV RMS Isolation Digital Isolator with 100 Mbps Data Rate and

Product Specification

1. Core Functionality

• Reinforced Isolation Capability: Provides 5 kV RMS isolation voltage for 1 minute and 2.5 kV RMS continuous working isolation voltage, meeting IEC 61010-1, IEC 60747-5-5 and UL 1577 safety standards. It effectively isolates high-voltage transients, eliminates ground loop interference, and protects low-voltage control circuits from high-voltage side faults.
• Dual-Channel Configuration: Equipped with 2 independent isolation channels, supporting configurable unidirectional or bidirectional data transmission with CMOS/LVCMOS logic level compatibility. This flexible architecture adapts to diverse interface isolation requirements in compact system designs.
• High-Speed & Low-Latency Transmission: Delivers a maximum data rate of 100 Mbps with ultra-low propagation delay, ensuring real-time signal transmission for time-critical applications such as motor control and high-speed communication interfaces.
• Automotive-Grade Robustness: Operates stably over a wide temperature range of -40°C to +125°C, with excellent ESD protection (±15 kV HBM) and high electromagnetic interference (EMI) immunity. It maintains reliable performance under extreme conditions of vibration, humidity, and voltage fluctuation.
• Low Power Consumption: Features ultra-low quiescent current and a shutdown mode, minimizing power dissipation in battery-powered automotive subsystems and low-power industrial equipment.
