Product details
Overview
ISO7763QDBQRQ1 from Texas Instruments is a reinforced six-channel digital isolator for automotive systems, delivering 100Mbps data rate, ±100kV/μs CMTI, and 3000VRMS isolation (DBQ package). It operates across 2.25V–5.5V supply rails with level translation and features default-low output logic (F-suffix variant). Used in EV traction inverters and battery management systems where high-noise immunity and functional safety compliance are critical.
For engineers reviewing the ISO7763QDBQRQ1 datasheet, ISO7763QDBQRQ1 pinout, ISO7763QDBQRQ1 application, or ISO7763QDBQRQ1 equivalent, this page provides verified technical context, automotive-grade safety certifications (AEC-Q100 Grade 1, VDE 0884-17, UL 1577), real-world EMC performance metrics, and validated alternative options for BMS and inverter subsystem design.
Technical Context
The ISO7763QDBQRQ1 implements dual capacitive SiO₂ isolation barriers per channel, enabling reinforced insulation with 12.8kV surge capability and >30-year lifetime projection. Its architecture supports asymmetric supply operation (VCCI ≠ VCCO) and bidirectional signal routing configurations - specifically three forward + three reverse channels as defined by its pin mapping.
It integrates UVLO detection (2.25V rising / 1.8V falling threshold) and meets IEC 61000-4-2 ±8kV contact ESD across the barrier. The device is functionally safety-capable with documented FIT rates and failure mode analysis available for ISO 26262 ASIL-B system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - supports high-speed CAN FD, SPI, and PWM feedback loops in traction inverters without timing bottlenecks. |
| Isolation Rating | 3000 VRMS (UL 1577, DBQ package) - enables safe separation between 400V+ battery domains and low-voltage MCU control logic. |
| CMTI | ±100 kV/μs typical - rejects fast transients from IGBT switching noise in motor drives without signal corruption. |
| Supply Range | 2.25 V to 5.5 V on both sides - allows direct interface with 3.3V MCUs and 5V analog sensing circuits without level shifters. |
| Ambient Temp | –40°C to +125°C (AEC-Q100 Grade 1) - qualified for under-hood and powertrain module environments. |
| Propagation Delay | 11 ns typical at 5V - ensures sub-20ns channel-to-channel skew for synchronized gate driver control. |
| Power @ 100 Mbps | 21 mA (ICC1 + ICC2) at 3.3V - enables low-heat dissipation in space-constrained BMS modules. |
Pinout & Package
ISO7763QDBQRQ1 uses a 16-pin SSOP (DBQ) package measuring 4.90 mm × 3.90 mm, optimized for high-density automotive PCB layouts with creepage >3.7 mm and clearance >3.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA–INF | Input channels A–F | Logic-level inputs referenced to VCC1/GND1; accept 2.25–5.5V CMOS/LVCMOS signals. |
| OUTA–OUTF | Output channels A–F | Default-low outputs (F-suffix) referenced to VCC2/GND2; drive 4mA sink/source at 3.3V. |
| VCC1, GND1 | Input-side power | Supplies input buffer and logic; independent of output rail for true galvanic isolation. |
| VCC2, GND2 | Output-side power | Supplies output drivers; enables level translation between disparate voltage domains. |
| Isolation Barrier | Silicon dioxide (SiO₂) | Dual-capacitor structure certified to VDE 0884-17 for reinforced insulation up to 12.8kV surge. |
Key Features
| Feature | Design Value |

| On-board Charger (OBC) | DC/DC Converter Control |
|
Use Scenario: Isolating digital control signals between primary-side PFC controller and secondary-side LLC resonant controller. IC Role / Device Role / Timing Role: Provides six independent isolation paths for voltage reference, current limit, soft-start, and status flags across 600V+ isolation barrier. Use Value: Eliminates common-mode noise coupling that causes false triggering of OBC protection circuits during high-frequency switching. |
Use Scenario: Isolating feedback signals (output voltage, current, temperature) from isolated DC/DC converter to main vehicle ECU.

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 |
|---|---|---|---|
| ISO7763DWQ1 | Same functionality but in 16-pin SOIC (DW) package with 5000VRMS isolation rating and larger 10.3mm × 7.5mm footprint. | Preferred for industrial or non-space-constrained automotive modules requiring higher isolation voltage margin. | Select when board layout allows larger package and system requires >3000VRMS working voltage per UL 1577. |
| ADUM6603ARWZ-RL | Analog Devices' 6-channel isolator with integrated isolated DC-DC converter; 2.5kVRMS isolation; 150Mbps data rate; different pinout and no AEC-Q100 Grade 1 rating. | Suitable for space-limited designs needing single-chip isolation + power, but not for ASIL-B automotive safety-critical functions. | Choose only if isolated power is required and functional safety certification is not mandated for the subsystem. |
Compared with ISO7763QDBQRQ1, ISO7763DWQ1 offers higher isolation voltage in a larger package ideal for less dense layouts, while ADUM6603ARWZ-RL trades automotive qualification and reinforced insulation for integrated power - making it unsuitable for BMS or inverter control where AEC-Q100 and VDE 0884-17 compliance are mandatory.

FAQ
What is the isolation voltage rating for ISO7763QDBQRQ1?
The ISO7763QDBQRQ1 has a UL 1577-rated isolation voltage of 3000 VRMS, verified for the DBQ (SSOP-16) package. This rating applies to continuous working voltage under pollution degree 2 conditions and supports reinforced insulation per VDE 0884-17 with 4242 VPK maximum repetitive peak voltage. It is validated for use in 400V–800V EV battery domains.
Does ISO7763QDBQRQ1 support level translation between different supply voltages?
Yes, ISO7763QDBQRQ1 supports true bidirectional level translation: VCC1 and VCC2 can operate independently from 2.25V to 5.5V, allowing interfaces such as 1.8V FPGA logic to 5V sensor circuitry or 3.3V MCU to 5V gate driver logic. Input thresholds scale with VCCI, and output drive strength adapts to VCCO.
What does the 'F' suffix indicate in ISO7763QDBQRQ1?
The 'F' suffix in ISO7763QDBQRQ1 denotes default-low output behavior: when input power or signal is lost, all six outputs (OUTA–OUTF) assert logic low. This fail-safe state prevents unintended activation of downstream drivers or actuators in automotive safety-critical subsystems like BMS or inverter control.
Which safety standards does ISO7763QDBQRQ1 comply with?
ISO7763QDBQRQ1 is certified to DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation, UL 1577 (3000 VRMS), CSA IEC 62368-1, CQC GB4943.1, and TUV EN 62368-1. It carries AEC-Q100 Grade 1 qualification and supports functional safety development per ISO 26262 with documented FIT rates and failure mode analysis.
How does ISO7763QDBQRQ1 differ from ISO7760QDBQRQ1 in pin configuration?
ISO7763QDBQRQ1 implements a three-forward + three-reverse channel arrangement (INA→OUTA, INB→OUTB, INC→OUTC, OUTD←IND, OUTE←INE, OUTF←INF), whereas ISO7760QDBQRQ1 has all six channels unidirectional (input→output). This makes ISO7763QDBQRQ1 optimal for bidirectional protocols like isolated SPI or I²C, while ISO7760QDBQRQ1 suits six independent unidirectional signals.
