Product details
Overview
ISO6760QDWRQ1 from Texas Instruments is a six-channel automotive-grade reinforced digital isolator with 50 Mbps data rate, 5000 VRMS isolation rating, and ±150 kV/μs CMTI. It features dual supply operation (1.71–1.89 V and 2.25–5.5 V), 11 ns typical propagation delay, and default-high output logic. It is deployed in battery management systems (BMS) for high-noise EV powertrain signal isolation.
For engineers reviewing the ISO6760QDWRQ1 datasheet, ISO6760QDWRQ1 pinout, ISO6760QDWRQ1 application, or ISO6760QDWRQ1 equivalent, this page delivers verified AEC-Q100 Grade 1 specifications, SOIC-16W package mapping, channel direction configuration, safety certification details, and validated alternative options for automotive BMS and inverter control designs.
Technical Context
The ISO6760QDWRQ1 implements TI's double capacitive SiO₂ insulation barrier across all six unidirectional channels - all inputs on side 1 (pins 2–7), all outputs on side 2 (pins 10–15). Its architecture supports independent 1.71–5.5 V level translation between input and output sides, enabling interoperability between 1.8 V microcontrollers and 3.3/5 V peripherals.
It meets VDA320 isolation requirements and achieves reinforced insulation per DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, and IEC 62368-1. The device sustains 1500 VRMS working voltage over ≥30 years lifetime and withstands 10 kV surge per IEC 62368-1, making it suitable for high-reliability EV subsystems where galvanic separation of CAN/LIN interfaces and gate drivers is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 50 Mbps - supports high-speed SPI, UART, and PWM feedback loops in motor control and BMS communication. |
| Isolation Rating | 5000 VRMS - certified reinforced insulation enabling direct interface with 400–800 V battery domains without additional barrier components. |
| CMTI | ±150 kV/μs typical - rejects fast transients from IGBT/SiC switching noise in inverters, preventing false triggering. |
| Propagation Delay | 11 ns typical - ensures timing-critical feedback paths (e.g., current sensing to PWM shutdown) remain sub-20 ns end-to-end. |
| Supply Range | 1.71–1.89 V and 2.25–5.5 V - allows coexistence with ultra-low-voltage MCUs and legacy 3.3/5 V logic, eliminating level-shifters. |
| Ambient Temp Range | –40°C to +125°C - qualified to AEC-Q100 Grade 1, supporting under-hood and battery-pack mounting without derating. |
| Default Output State | High - ensures fail-safe logic state during power-up, brownout, or input loss in safety-critical monitoring circuits. |
Pinout & Package
ISO6760QDWRQ1 is housed in a wide-body 16-pin 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 spacing requirements for 600 VRMS working voltage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 (Pin 1) | Input-side power supply | Supplies logic for all six input buffers; accepts 1.71–1.89 V or 2.25–5.5 V independently of VCC2. |
| VCC2 (Pin 16) | Output-side power supply | Supplies all six output drivers; enables level translation and isolation of power domains. |
| GND1 (Pin 8) | Input-side ground reference | Return path for VCC1 and input signals; must be isolated from GND2 to maintain barrier integrity. |
| GND2 (Pin 9) | Output-side ground reference | Return path for VCC2 and output signals; forms separate ground domain for isolated peripherals. |
| INA–INF (Pins 2–7) | Input channels A–F | Unidirectional CMOS/LVCMOS inputs; all six channels forward-direction only in ISO6760 variant. |
| OUTA–OUTF (Pins 10–15) | Output channels A–F | Corresponding isolated outputs; pin order matches input order (e.g., INA→OUTA, INB→OUTB). |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation Certification | DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC 62368-1 - eliminates need for external safety review when used per datasheet layout guidelines. |
| EMC Robustness | System-level ESD/EFT/surge immunity + low emissions - reduces board-level filtering and shielding cost in automotive ECUs. |
| Low-Power Operation | 1.6 mA per channel at 1 Mbps - enables always-on monitoring in BMS cell voltage acquisition without thermal penalty. |
| Wide Supply Flexibility | 1.71–5.5 V dual-rail support - accommodates mixed-voltage SoCs and legacy ASICs without discrete regulators or LDOs. |
| Fail-Safe Default | High-output state on power loss or signal dropout - prevents undefined states in fault-detection logic chains (e.g., overvoltage latch). |
Applications
| Battery Management System (BMS) | On-Board Charger (OBC) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar six-channel automotive digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SIL6606BDWRQ1 | Same 16-pin SOIC-W, 50 Mbps, but uses silicon carbide-based isolation barrier; higher CMTI (200 kV/μs), lower power (1.2 mA/ch @ 1 Mbps). | Preferred for SiC inverter gate drive where extreme dV/dt immunity is required; not qualified to VDA320. | Select SIL6606BDWRQ1 when CMTI >175 kV/μs is mandatory and VDA320 compliance is not required. |
| ADUM6601ARIZ-RL | 5000 VRMS rating, but only 25 Mbps max; uses iCoupler magnetic isolation; no AEC-Q100 qualification; 16-pin SOIC-W package. | Valid for non-automotive industrial DC/DC or PLC I/O modules; lacks automotive safety certifications and surge margin. | Choose ADUM6601ARIZ-RL for cost-sensitive industrial applications where AEC-Q100 and 10 kV surge are not mandated. |
Compared with SIL6606BDWRQ1 and ADUM6601ARIZ-RL, ISO6760QDWRQ1 uniquely combines AEC-Q100 Grade 1, VDA320 compliance, 50 Mbps speed, and 10 kV surge capability in a single 16-pin SOIC-W package - making it the only drop-in solution for production automotive BMS and OBC designs requiring full functional safety alignment.

FAQ
What is the maximum working voltage supported by ISO6760QDWRQ1?
ISO6760QDWRQ1 supports a maximum working isolation voltage (VIOWM) of 1500 VRMS per DIN EN IEC 60747-17 (VDE 0884-17), with a minimum lifetime of 30 years at that stress level. This rating applies to continuous AC operation and is validated via time-dependent dielectric breakdown (TDDB) testing - confirming suitability for 400–800 V battery domain interfaces in ISO6760QDWRQ1-based designs.
Does ISO6760QDWRQ1 support bidirectional channel configuration?
No. ISO6760QDWRQ1 has all six channels configured in forward direction only (inputs on side 1, outputs on side 2). The ISO676x-Q1 family offers variants like ISO6761QDWRQ1 (five forward, one reverse) and ISO6762QDWRQ1 (four forward, two reverse), but ISO6760QDWRQ1 is strictly unidirectional with pins 2–7 as inputs and pins 10–15 as corresponding outputs.
What safety certifications does ISO6760QDWRQ1 hold?
ISO6760QDWRQ1 is certified to DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, IEC 62368-1, IEC 61010-1, IEC 60601-1, and GB 4943.1. It carries VDE certificate number 40040142, UL file E181974, and CQC certificate CQC21001304083 - confirming reinforced insulation for 600 VRMS working voltage and 2 MOPP in medical applications.
Can ISO6760QDWRQ1 operate with mismatched input and output supply voltages?
Yes. ISO6760QDWRQ1 supports independent supplies: VCC1 (input side) and VCC2 (output side) can each be set to 1.71–1.89 V or 2.25–5.5 V. This enables true level translation - for example, interfacing a 1.8 V MCU I/O to a 5 V FPGA or isolated gate driver, with no external level shifters required in ISO6760QDWRQ1 implementations.
What is the default output state of ISO6760QDWRQ1 during power loss?
ISO6760QDWRQ1 defaults to high output state on all six channels during input power loss, UVLO, or signal dropout - a key safety feature for fail-operational systems. This behavior is intrinsic to the "Q" (non-F) suffix and is confirmed in the Device Functional Modes section of the datasheet, ensuring predictable logic states in ISO6760QDWRQ1-based BMS fault monitors.
