Product details
Overview
ISO6720FQDWVRQ1 from Texas Instruments is a reinforced dual-channel automotive digital isolator with 5000VRMS isolation rating (DWV-8 package), 50Mbps data rate, and ±150kV/μs CMTI. It features default-low output logic (F-suffix), operates across 1.71V–5.5V dual supplies, and is AEC-Q100 Grade 1 qualified (–40°C to +125°C) for battery management systems and traction inverters.
For engineers reviewing the ISO6720FQDWVRQ1 datasheet, ISO6720FQDWVRQ1 pinout, ISO6720FQDWVRQ1 application, or ISO6720FQDWVRQ1 equivalent, key selection criteria include reinforced isolation certification (VDE 0884-17, UL 1577), dual-supply level translation capability, low 11ns propagation delay, and robust EMC performance including ±8kV IEC 61000-4-2 contact ESD protection across the barrier.
Technical Context
The ISO6720FQDWVRQ1 implements TI's double capacitive SiO₂ insulation barrier, enabling galvanic isolation between two independent CMOS/LVCMOS domains. Its two channels are unidirectional (input→output on both sides), supporting isolated signal transmission in high-noise powertrain subsystems where ground separation and voltage domain bridging are critical.
It supports independent 1.71V–1.89V or 2.25V–5.5V supplies on each side, enabling 1.71V–5.5V level translation. The device includes integrated UVLO detection (1.53V rising / 1.1V falling threshold) and failsafe default-low output behavior during input loss-critical for functional safety–capable automotive designs.
Key Specifications

Pinout & Package
ISO6720FQDWVRQ1 uses the DWV-8 SOIC package (5.85mm × 11.50mm body, 8-pin wide-body SOIC), optimized for creepage/clearance compliance in high-voltage automotive systems. Reinforced isolation requires ≥8.5mm external clearance and creepage between sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Input-side power supply | Supplies logic and input buffer; accepts 1.71V–1.89V or 2.25V–5.5V; powers INA/INB inputs |
| VCC2 | Output-side power supply | Supplies output buffer and OUTA/OUTB drivers; independent of VCC1 for level translation |
| INA | Channel A input | Digital input referenced to GND1; compatible with 1.71V–5.5V logic thresholds (VIH = 0.7×VCCI) |
| INB | Channel B input | Digital input referenced to GND1; identical electrical specs to INA |
| OUTA | Channel A output | Default-low (F-suffix) CMOS output referenced to GND2; drives 1mA load at 1.8V with 0.1V VOL |
| OUTB | Channel B output | Default-low CMOS output referenced to GND2; matches OUTA timing and drive strength |
| GND1 | Input-side ground | Reference for VCC1, INA, INB; must be isolated from GND2 by PCB layout and system grounding |
| GND2 | Output-side ground | Reference for VCC2, OUTA, OUTB; forms isolated domain with GND1 across SiO₂ barrier |

|---|---|
|
Use Scenario: Isolating cell voltage monitoring ADC serial interfaces and pack current sensor outputs in 400V/800V EV battery packs. IC Role / Device Role / Timing Role: Dual-channel isolator bridges MCU SPI bus (side 1) to isolated ADCs/sensors (side 2), maintaining precise timing for synchronized sampling. Use Value: 11ns propagation delay and 50Mbps rate preserve ADC timing resolution; 5000VRMS rating satisfies IEC 62621 creepage requirements for Class C battery systems. |
Use Scenario: Transmitting PWM gate-drive signals and fault feedback from IGBT/SiC half-bridges to MCU in high-power traction inverters. IC Role / Device Role / Timing Role: Unidirectional isolator conveys PWM commands (INA→OUTA, INB→OUTB) while blocking noise from switching nodes. Use Value: ±150kV/μs CMTI prevents false turn-on during 1200V/ns dV/dt events; reinforced isolation eliminates need for optocoupler-based redundancy. |
| On-Board Charger (OBC) | DC/DC Converter Control |
|
Use Scenario: Isolating digital control signals between primary-side controller and secondary-side regulation circuitry in bidirectional OBCs. IC Role / Device Role / Timing Role: Provides galvanic separation for communication (e.g., PMBus) and enable/status lines across 600V+ isolation barriers. Use Value: Dual 1.71V–5.5V supply support enables direct interfacing with 1.8V MCU peripherals and 3.3V analog sensing ICs; ±8kV ESD protects against coupling from AC line surges. |
Use Scenario: Isolating feedback signals (voltage/current sense) and control outputs in high-efficiency 48V–12V automotive DC/DC converters. IC Role / Device Role / Timing Role: Transmits isolated analog-to-digital converter outputs and PWM duty cycle commands across the isolation barrier. Use Value: Low 1.8mA/channel quiescent current minimizes standby losses; 1.71V minimum supply allows integration with ultra-low-power microcontrollers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel reinforced automotive digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8620ED-B-IS | 3750VRMS isolation (D-8), 100Mbps max, 13ns propagation delay, 2.5–5.5V only | Limited to basic insulation; not VDE-reinforced or AEC-Q100 Grade 1 qualified | Use where lower isolation voltage suffices and higher speed justifies trade-off in safety certification |
| ADUM121N1BRZ-RL7 | 3000VRMS (SOIC-8), 150Mbps, 15ns delay, 1.7–5.5V, no automotive qualification | No AEC-Q100 or VDE 0884-17 certification; lacks system-level ESD/surge immunity claims | Select for non-automotive industrial applications needing higher bandwidth but not functional safety compliance |
Compared with Si8620ED-B-IS and ADUM121N1BRZ-RL7, ISO6720FQDWVRQ1 uniquely delivers 5000VRMS reinforced isolation with AEC-Q100 Grade 1 and VDE 0884-17 certification in a single package-enabling direct use in ASIL-B safety islands without additional validation overhead.

FAQ
What is the isolation rating and certification status of ISO6720FQDWVRQ1?
ISO6720FQDWVRQ1 provides 5000VRMS reinforced isolation per UL 1577 and DIN EN IEC 60747-17 (VDE 0884-17), with certifications from UL, VDE, CSA, TUV, and CQC. It meets AEC-Q100 Grade 1 (–40°C to +125°C) and VDA320 requirements, making it suitable for ASIL-B/C automotive safety applications without external redundancy.
How does the F-suffix affect the output behavior of ISO6720FQDWVRQ1?
The 'F' suffix in ISO6720FQDWVRQ1 denotes default-low output logic: when input power (VCC1) or signal is lost, both OUTA and OUTB drive low. This fail-safe state ensures controlled shutdown of downstream circuits like gate drivers or ADC references-critical for functional safety in traction inverters and BMS.
Can ISO6720FQDWVRQ1 operate with mismatched supply voltages on each side?
Yes. ISO6720FQDWVRQ1 supports independent supplies: VCC1 and VCC2 can each be set to 1.71V–1.89V or 2.25V–5.5V. This enables true 1.71V–5.5V level translation-for example, interfacing a 1.8V MCU I/O with a 5V analog front-end-without external level shifters.
What is the maximum data rate and propagation delay of ISO6720FQDWVRQ1?
ISO6720FQDWVRQ1 supports up to 50Mbps data rate with 11ns typical propagation delay and tight channel-to-channel skew. These specifications maintain signal integrity in high-speed interfaces such as isolated SPI for BMS ADCs or PWM command transmission in 800V traction inverters.
Does ISO6720FQDWVRQ1 include system-level EMC protection?
Yes. ISO6720FQDWVRQ1 integrates system-level ESD, EFT, and surge immunity: ±8kV IEC 61000-4-2 contact discharge across the isolation barrier, plus low emissions design. This eliminates the need for external TVS diodes or filtering on isolated signal paths in automotive ECU designs.
