Product details
Overview
ISO7763FQDWRQ1 from Texas Instruments is a reinforced six-channel digital isolator for automotive systems, delivering 100Mbps data rate, ±100kV/μs CMTI, and 5000VRMS isolation (DW package). It features default-low output logic, 2.25V–5.5V dual-supply operation, and AEC-Q100 Grade 1 qualification (–40°C to +125°C ambient) for use in traction inverters and battery management systems.
For engineers reviewing the ISO7763FQDWRQ1 datasheet, ISO7763FQDWRQ1 pinout, ISO7763FQDWRQ1 application, or ISO7763FQDWRQ1 equivalent, key selection criteria include reinforced insulation certification (VDE 0884-17, UL 1577), channel direction configuration (3 forward / 3 reverse), low-power consumption at 1Mbps (2.4mA typical total supply current), and SOIC-16 (DW) package compatibility with automotive PCB layouts.
Technical Context
The ISO7763FQDWRQ1 implements dual capacitive SiO₂ isolation barriers per channel, enabling robust noise immunity across high dv/dt environments in EV powertrain subsystems. Its functional safety-capable architecture supports ISO 26262 ASIL-B system integration with documented safety analysis support.
It operates with independent input (VCCI/GNDI) and output (VCCO/GNDO) supplies, allowing level translation between 2.25V and 5.5V domains. The device's 3-forward/3-reverse channel configuration (INA–INC inputs driving OUTA–OUTC; IND–INF inputs driven by OUTD–OUTF) enables bidirectional signal routing in CAN/LIN bus interfaces and gate driver feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 100 Mbps maximum - supports high-speed serial communication in motor control PWM feedback and isolated ADC interfaces. |
| Isolation rating | 5000 VRMS (UL 1577) - enables reinforced insulation for 600 VRMS working voltage in traction inverter gate drive circuits. |
| CMTI | ±100 kV/μs typical - ensures reliable operation under fast transient noise in high-power switching nodes (e.g., IGBT/SiC half-bridges). |
| Supply range | 2.25 V to 5.5 V per side - allows direct interfacing with 3.3V microcontrollers and 5V analog front-ends without level shifters. |
| Propagation delay | 11 ns typical at 5 V - meets timing constraints for real-time fault detection and fast-loop current sensing in OBC and DC/DC converters. |
| Default output state | Low (F-suffix) - provides fail-safe logic state during power loss in safety-critical monitoring paths (e.g., BMS cell voltage supervision). |
| Ambient temperature | –40°C to +125°C - qualified for under-hood and power module mounting locations per AEC-Q100 Grade 1. |
Pinout & Package
ISO7763FQDWRQ1 uses the Wide-SOIC-16 (DW) package (10.30 mm × 10.30 mm), optimized for high-voltage creepage (>8 mm) and thermal performance (RθJA = 60.3°C/W) in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VCC1, VCC2 | Independent input-side and output-side power supplies - enable galvanic separation and level translation between controller and power stage domains. |
| 2–7 | INA, INB, INC, IND, INE, INF | Logic-level digital inputs - configured as 3 forward (INA–INC) and 3 reverse (IND–INF) channels per ISO7763 functional mode. |
| 8, 9 | GND1, GND2 | Input-side and output-side ground references - maintain isolation integrity; require separate PCB ground planes with no direct connection. |
| 10–15 | OUTF, OUTE, OUTD, OUTC, OUTB, OUTA | CMOS/LVCMOS outputs - deliver default-low state on power loss; support 4 mA sink/source at 5 V for direct MCU or driver IC interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced insulation certification | DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, CSA 62368-1 - satisfies functional safety requirements for ASIL-B automotive subsystems without external protection components. |
| Robust EMC performance | ±8 kV IEC 61000-4-2 contact ESD across barrier, system-level surge immunity - reduces need for external TVS diodes in noisy EV power electronics environments. |
| Low-power operation | 2.4 mA typical total supply current at 1 Mbps (3.3 V) - extends runtime in always-on BMS monitoring circuits and lowers thermal load in sealed enclosures. |
| Wide operating temperature | –40°C to +125°C ambient - supports placement adjacent to power semiconductors in traction inverters and onboard chargers without derating. |
| Channel direction flexibility | 3 forward + 3 reverse configuration - enables single-package isolation of bidirectional signals such as SPI clock/data and gate driver status feedback in compact OBC designs. |
Applications
| Battery Management System (BMS) | Traction Inverter Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar six-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO7763DWRQ1 | Same DW package and 3F/3R channel configuration, but default-high output (no F suffix); 2.4 mA typical ICC at 1 Mbps matches ISO7763FQDWRQ1. | Used where active-high fault signaling or MCU reset assertion is required; not suitable for fail-low safety paths. | Select ISO7763DWRQ1 only when system logic requires asserted-high default state during power loss. |
| ADUM7643CRQZ-RL7 | 6-channel, 100 Mbps, default-low, but rated for 3750 VRMS (CSA/UL), not reinforced per VDE 0884-17; 15 ns propagation delay vs. 11 ns. | Approved for industrial, not automotive AEC-Q100 Grade 1; lacks VDE certification required for EV traction systems. | Consider ADUM7643CRQZ-RL7 only for non-automotive, non-safety-critical 3.75 kVRMS applications where VDE compliance is not mandated. |
Compared with ISO7763DWRQ1 and ADUM7643CRQZ-RL7, ISO7763FQDWRQ1 uniquely combines AEC-Q100 Grade 1 qualification, VDE 0884-17 reinforced insulation, 5000 VRMS rating, and 3F/3R channel direction - making it the only option certified for ASIL-B traction inverter and BMS isolation in production EV platforms.

FAQ
What is the isolation voltage rating of the ISO7763FQDWRQ1?
The ISO7763FQDWRQ1 has a 5000 VRMS isolation rating per UL 1577 (DW package), with reinforced insulation certified to DIN EN IEC 60747-17 (VDE 0884-17). This enables safe operation at up to 1500 VRMS working voltage in automotive applications, validated for 30-year lifetime under continuous stress conditions.
Does the ISO7763FQDWRQ1 support level translation between different supply voltages?
Yes, the ISO7763FQDWRQ1 supports independent 2.25V–5.5V supplies on input (VCCI/GNDI) and output (VCCO/GNDO) sides, enabling seamless level translation - for example, interfacing a 3.3V microcontroller to a 5V gate driver without external level shifters. This capability is explicitly specified in the datasheet's Recommended Operating Conditions table.
What does the 'F' suffix in ISO7763FQDWRQ1 indicate?
The 'F' suffix denotes default-low output behavior: when input power is lost or input signals are invalid, all six outputs (OUTA–OUTF) drive low. This fail-safe state is critical in automotive safety systems like BMS contactor control, where de-energized is the safe condition. Non-F variants (e.g., ISO7763DWRQ1) default high.
Which package type does ISO7763FQDWRQ1 use, and why is it suited for automotive applications?
ISO7763FQDWRQ1 uses the Wide-SOIC-16 (DW) package (10.30 mm × 10.30 mm), offering >8 mm creepage/clearance and 5000 VRMS isolation. Its RθJA of 60.3°C/W and AEC-Q100 qualification make it ideal for under-hood placement near power modules, where thermal stability and high-voltage robustness are essential in EV traction systems.
How does the ISO7763FQDWRQ1 achieve high electromagnetic compatibility in noisy automotive environments?
The ISO7763FQDWRQ1 achieves robust EMC through double capacitive SiO₂ isolation barriers, ±100 kV/μs CMTI, ±8 kV IEC 61000-4-2 contact ESD across the barrier, and low emissions design. These features eliminate external filtering in high-noise zones like inverter compartments - verified by system-level EFT and surge immunity testing per ISO 11452 standards.
