Product details
Overview
ISO6763QDWRQ1 from Texas Instruments is a six-channel automotive-grade reinforced digital isolator with 50 Mbps data rate, 5000 VRMS isolation rating, ±150 kV/μs CMTI, and AEC-Q100 Grade 1 qualification (–40°C to +125°C ambient). It features dual supply rails (1.71–5.5 V), 1.71–5.5 V level translation, and default-high output logic for use in battery management systems and motor control interfaces.
For engineers reviewing the ISO6763QDWRQ1 datasheet, ISO6763QDWRQ1 pinout, ISO6763QDWRQ1 application, or ISO6763QDWRQ1 equivalent, key selection criteria include reinforced isolation compliance (VDE 0884-17, UL 1577), channel direction configuration (4 forward / 2 reverse), SOIC-16 wide-body package footprint, and automotive EMC robustness for EV powertrain subsystems.
Technical Context
The ISO6763QDWRQ1 implements TI's double capacitive SiO₂ insulation barrier across all six channels, enabling galvanic isolation between independent input (VCCI/GNDI) and output (VCCO/GNDO) domains. Its architecture supports asymmetric supply operation - VCCI and VCCO may differ (e.g., 1.8 V on side 1, 5 V on side 2) while maintaining full signal integrity and level translation.
Unlike earlier generations, ISO6763QDWRQ1 delivers enhanced system-level ESD/EFT/surge immunity per VDA320 and meets IEC 62368-1, IEC 61010-1, and IEC 60601-1 safety standards. Its pinout places all inputs on the left side (pins 2–7) and outputs on the right (pins 10–15), with dedicated isolated power and ground terminals (VCC1/VCC2, GND1/GND2) at opposite ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

ISO6763QDWRQ1 is housed in a 16-pin Wide-SOIC (DW) package measuring 10.30 mm × 7.50 mm, with creepage and clearance >8 mm and internal DTI >17 µm - compliant with reinforced insulation requirements for automotive 600 VRMS working voltage systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 (Pin 1) | Input-side power supply | Supplies logic and input buffer circuitry; accepts 1.71–5.5 V; UVLO thresholds at 1.53 V (rising) and 1.1 V (falling). |

| GND1 (Pin 8) | Input-side ground | Reference for VCC1 and all input pins; must be separated from GND2 by PCB isolation barrier. |
| GND2 (Pin 9) | Output-side ground | Reference for VCC2 and all output pins; completes isolated power domain separation. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation Certification | DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC 62368-1, IEC 61010-1, IEC 60601-1 - eliminates need for external safety capacitors in medical and industrial equipment. |

| Low-Power Operation | 1.6 mA per channel at 1 Mbps (typical) - enables always-on monitoring in low-power BMS sleep modes without compromising responsiveness. |
| Surge Withstand | 10 kV peak surge capability - protects downstream MCU GPIOs from inductive kickback in 400 V–800 V battery disconnect circuits. |
| Default-High Output Logic | No suffix 'F' indicates default-high behavior during input loss or UVLO - ensures fail-safe activation of isolated fault latches in motor controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar six-channel reinforced digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6763FDWRQ1 | Identical pinout and specs, but default-low output ('F' suffix) instead of default-high. | Required where fail-safe logic mandates low-state output during power loss (e.g., disable-on-fault motor drives). | Select ISO6763FDWRQ1 only when hardware reset strategy depends on active-low assertion; otherwise ISO6763QDWRQ1 provides broader compatibility with existing MCU GPIO configurations. |
| ADUM6630ARIZ-RL | 6-channel, 50 Mbps, 3750 VRMS isolation (not reinforced), 2.7–5.5 V supply, no AEC-Q100 qualification. | Limited to non-safety-critical industrial automation; lacks VDE/UL reinforced certification and automotive temperature range. | Use ADUM6630ARIZ-RL only in cost-sensitive non-automotive designs where 3750 VRMS basic insulation suffices and AEC-Q100 is not mandated. |
Compared with ISO6763FDWRQ1, ISO6763QDWRQ1 offers identical performance but inverted fail-safe behavior - critical for BMS contactor control where open-circuit defaults must assert 'on'. Versus ADUM6630ARIZ-RL, ISO6763QDWRQ1 delivers certified reinforced isolation, AEC-Q100 Grade 1 operation, and 5000 VRMS rating essential for functional safety compliance in ISO 26262 ASIL-B/C systems.

FAQ
What is the default output state of ISO6763QDWRQ1 during power-up or input loss?
The ISO6763QDWRQ1 has a default-high output configuration - all six outputs (OUTA–OUTF) drive high when VCC1 or VCC2 is below UVLO threshold or when input signals are absent. This behavior is intrinsic to the 'Q' variant (non-F suffix) and ensures fail-safe activation of downstream latches or enable lines in BMS and inverter control applications. The ISO6763QDWRQ1 maintains this state until valid input transitions occur and supplies stabilize within operating range.
Does ISO6763QDWRQ1 support independent input and output supply voltages?
Yes, ISO6763QDWRQ1 fully supports independent VCCI (Pin 1) and VCCO (Pin 16) supplies ranging from 1.71–1.89 V or 2.25–5.5 V each. This enables true level translation - for example, interfacing a 1.8 V MCU I/O bank to a 5 V isolated ADC or gate driver. The device guarantees correct logic thresholds and drive strength across all supported combinations, with VIH = 0.7×VCCI and VOH = VCCO – 0.4 V (at 4 mA load) verified per datasheet Section 6.9–6.15.
How does ISO6763QDWRQ1 achieve its ±150 kV/μs CMTI rating?
ISO6763QDWRQ1 achieves ±150 kV/μs typical common-mode transient immunity through TI's proprietary double capacitive SiO₂ isolation barrier and optimized on-die noise rejection circuitry. The barrier's high dielectric strength and low coupling capacitance (~1 pF) minimize transient-induced displacement current, while internal hysteresis and fast response comparators suppress false toggling. This is validated per Figure 7-3 in the datasheet under 1200 V step-edge common-mode stress, making ISO6763QDWRQ1 suitable for noisy inverter gate driver feedback paths.
Which safety certifications apply to ISO6763QDWRQ1, and what do they cover?
ISO6763QDWRQ1 holds DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC 62368-1, IEC 61010-1, and IEC 60601-1 certifications. These validate its 5000 VRMS reinforced insulation, 1500 VRMS working voltage lifetime, 7071 VPK transient rating, and 10 kV surge capability. Certifications cover construction (DTI >17 µm, CTI >600 V), material group (I), pollution degree (2), and climatic category (40/125/21), enabling direct use in ASIL-B/C automotive systems without additional system-level proof.
Can ISO6763QDWRQ1 replace older TI isolators like ISO7763 in automotive designs?
Yes, ISO6763QDWRQ1 is a pin-to-pin upgrade to ISO7763QDWRQ1 and other prior-generation 6-channel isolators. It retains identical SOIC-16 DW package, pinout, and footprint while adding VDA320 compliance, improved CMTI (±150 kV/μs vs. ±100 kV/μs), updated VDE 0884-17 certification, and enhanced surge immunity (10 kV vs. 8 kV). No PCB changes are required, and firmware remains compatible - only design revalidation per updated safety and EMC test plans is needed for production release.
