Product details
Overview
ISO7763QDWRQ1 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), with dual 2.25V–5.5V supply domains enabling level translation between isolated domains. It features default-low output logic (F-suffix variant), AEC-Q100 Grade 1 qualification (–40°C to +125°C), and VDE/UL/CSA/TUV safety certifications.
For engineers reviewing the ISO7763QDWRQ1 datasheet, ISO7763QDWRQ1 pinout, ISO7763QDWRQ1 application, or ISO7763QDWRQ1 equivalent, key selection criteria include reinforced insulation rating, channel direction configuration (3 forward / 3 reverse), low-power operation at 100Mbps, and compatibility with CAN/LIN bus isolation in high-noise EV powertrain subsystems.
Technical Context
The ISO7763QDWRQ1 implements dual capacitive SiO₂ isolation barriers per channel, supporting asymmetric supply operation (VCCI ≠ VCCO) and bidirectional voltage translation across the barrier. Its architecture enables independent input/output ground domains (GNDI/GNDO) and supports fail-safe default-low output behavior upon signal loss.
It achieves robust EMC performance via optimized layout and chip-scale shielding, meeting IEC 61000-4-2 ±8kV contact ESD across the barrier and system-level surge immunity up to 12.8kV peak. The device is certified to DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and UL 1577 for 5000VRMS withstand voltage in SOIC (DW-16) packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - supports high-speed serial interfaces including CAN FD and isolated SPI in traction inverters. |
| Isolation Rating | 5000 VRMS (UL 1577) - enables reinforced insulation for functional safety-critical EV subsystems operating at 400–800V battery potentials. |
| CMTI | ±100 kV/μs typical - prevents false triggering during fast transients in motor drive gate driver feedback loops. |
| 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 5V - ensures tight timing alignment in real-time control loops such as BMS cell monitoring and DC/DC converter regulation. |
| Ambient Temp | –40°C to +125°C - qualified for under-hood and powertrain locations per AEC-Q100 Grade 1. |
| Power @ 100Mbps | 21–28.4 mA total (ICC1+ICC2) at 5V - enables low-heat design in compact, sealed automotive modules. |
Pinout & Package
ISO7763QDWRQ1 is housed in a wide-SOIC (DW-16) package measuring 10.30 mm × 10.30 mm (including pins), with creepage/clearance >8 mm and reinforced insulation per VDE 0884-17.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1, VCC2 | Input-side and output-side power supplies | Independent 2.25–5.5V domains enable level translation; UVLO thresholds ensure clean startup/reset across both sides. |
| GND1, GND2 | Input-side and output-side ground references | Galvanically isolated grounds prevent ground-loop noise coupling in high-dV/dt environments like inverter switching nodes. |
| INA–INF | Logic inputs (6 channels) | All inputs accept 2.25–5.5V CMOS/LVCMOS levels; hysteresis (0.1–0.2×VCCI) rejects noise on long traces in noisy chassis environments. |
| OUTA–OUTF | Logic outputs (6 channels) | Default-low (F-suffix) behavior ensures safe state during MCU reset or supply brownout in safety-critical paths. |
| Channel Direction | 3 forward (A–C), 3 reverse (D–F) | Enables bidirectional signal routing (e.g., PWM + fault feedback) across isolation barrier without external logic inversion. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 5000 VRMS UL rating and VDE 0884-17 certification - meets ASIL-D requirements for battery disconnect units and inverter control. |
| Automotive Qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient) - validated for continuous operation in engine bay and power electronics enclosures. |
| High CMTI | ±100 kV/μs common-mode transient immunity - maintains data integrity during 1000V/μs switching events in 800V traction inverters. |
| Low-Power Operation | 4.2 mA typical per side at 1 Mbps (3.3V) - reduces thermal load in space-constrained BMS sensor modules. |

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-16 package and pinout, but non-automotive grade (commercial temp range –40°C to +105°C); lacks AEC-Q100 qualification and some safety certifications. | Not suitable for under-hood automotive use; limited to industrial or consumer applications where extended temperature and functional safety are not required. | Select only if cost sensitivity outweighs automotive qualification needs and safety certification is not mandated by end-equipment standards. |
| ADUM6603ARWZ-RL | Integrated isolated DC-DC converter (3.3V output); 6-channel, 25Mbps max; lower CMTI (75 kV/μs); different pinout and no AEC-Q100 Grade 1 rating. | Reduces external power supply complexity but sacrifices speed and noise immunity; unsuitable for high-speed CAN FD or SiC gate drive feedback. | Choose when board space is constrained and isolated power is needed, but avoid in high-noise, high-speed automotive powertrain roles. |
Compared with ISO7763DWRQ1, ISO7763QDWRQ1 adds AEC-Q100 Grade 1 qualification and full automotive safety certifications, while ADUM6603ARWZ-RL trades speed and CMTI for integrated power - making ISO7763QDWRQ1 the only option meeting 100Mbps, ±100kV/μs, and ASIL-D-ready requirements in EV power systems.

FAQ
What is the isolation voltage rating of the ISO7763QDWRQ1?
The ISO7763QDWRQ1 has a UL 1577-rated isolation voltage of 5000 VRMS for 60 seconds in the DW-16 SOIC package. This reinforced insulation rating is certified per DIN EN IEC 60747-17 (VDE 0884-17) and supports safety-critical automotive applications up to 800V battery systems. The device also achieves 12.8kV peak surge capability in oil per IEC 62368-1.
Does the ISO7763QDWRQ1 support level translation between different supply voltages?
Yes, the ISO7763QDWRQ1 supports true bidirectional level translation: VCCI and VCCO can operate independently from 2.25V to 5.5V each. For example, it can translate 3.3V logic on the input side to 5V logic on the output side, or vice versa - eliminating external level shifters in mixed-voltage automotive ECUs. Input thresholds scale with VCCI (0.3–0.7×VCCI), ensuring compatibility across the full supply range.
What is the default output state of the ISO7763QDWRQ1 during power loss or input signal dropout?
The ISO7763QDWRQ1 is an "F-suffix" part, meaning its outputs default to LOW when input power or signal is lost. This fail-safe behavior is critical in automotive safety systems - for example, holding gate drivers disabled during MCU reset or brownout. The default state is implemented via internal circuitry and does not require external pull-down resistors.
How many channels and what direction configuration does the ISO7763QDWRQ1 provide?
The ISO7763QDWRQ1 provides six fully isolated digital channels with a fixed 3-forward / 3-reverse configuration: INA–INC are inputs driving OUTA–OUTC (forward), while IND–INF are inputs driving OUTD–OUTF (reverse). This enables simultaneous bidirectional communication - such as sending PWM commands in one direction and receiving fault/status signals in the other - without external logic inversion.
Is the ISO7763QDWRQ1 certified for functional safety applications in automotive systems?
Yes, the ISO7763QDWRQ1 is functional safety-capable with documentation available to support ISO 26262 ASIL-B and ASIL-D system development. It holds AEC-Q100 Grade 1 qualification, VDE 0884-17 reinforced insulation certification, and UL 1577 recognition - all essential for safety mechanisms in battery disconnect units, inverter controllers, and OBCs. TI provides FIT rate data, failure mode analysis, and diagnostic coverage guidance for system-level FMEDA.
