Product details
Overview
ISO7760FQDWRQ1 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 (F-suffix), 2.25V–5.5V dual-supply operation with level translation, and AEC-Q100 Grade 1 qualification (–40°C to +125°C ambient).
For engineers reviewing the ISO7760FQDWRQ1 datasheet, ISO7760FQDWRQ1 pinout, ISO7760FQDWRQ1 application, or ISO7760FQDWRQ1 equivalent, this page provides verified functional safety documentation support, SOIC-16 package layout guidance, BMS and traction inverter interface validation, and comparative analysis against ISO7761FQDWRQ1 and ISO7762FQDWRQ1.
Technical Context
The ISO7760FQDWRQ1 implements dual capacitive SiO₂ isolation barriers per channel, enabling reinforced insulation certified to VDE 0884-17, UL 1577, and IEC 62368-1. Its architecture supports asymmetric supply configurations (VCCI ≠ VCCO) and maintains signal integrity under ±1200V common-mode transients.
All six channels are unidirectional (input-to-output only), with input-side pins (INA–INF, VCC1, GND1) fully isolated from output-side pins (OUTA–OUTF, VCC2, GND2). The F-suffix denotes default-low output behavior during input loss or power-down, critical for fail-safe control in EV powertrain subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - enables high-speed CAN FD, SPI, and PWM feedback loops in real-time motor control. |
| Isolation Rating | 5000 VRMS (UL 1577) - meets reinforced insulation requirements for battery management system (BMS) high-voltage domain separation. |
| CMTI | ±100 kV/μs typical - ensures robust noise immunity in high-dV/dt environments like traction inverters and DC/DC converters. |
| Supply Range | 2.25 V to 5.5 V per side - supports mixed-voltage interfaces (e.g., 3.3V MCU ↔ 5V gate driver) without external level shifters. |
| Propagation Delay | 11 ns typical at 5 V - guarantees sub-22 ns round-trip latency for closed-loop current sensing and protection timing. |
| Ambient Temp Range | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and battery-pack mounting locations. |
| Power Consumption | 1.4 mA per channel at 1 Mbps - reduces thermal load in space-constrained automotive modules with multiple isolation channels. |
Pinout & Package
ISO7760FQDWRQ1 uses the Wide-SOIC (DW-16) package: 10.30 mm × 7.50 mm body size, 10.30 mm × 10.30 mm overall footprint including leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VCC1, VCC2 | Independent input-side and output-side power supplies - enables galvanic separation of logic and power domains. |
| 2–7 | INA, INB, INC, IND, INE, INF | Dedicated CMOS/LVCMOS inputs - all on primary (VCC1/GND1) side; no shared logic rails across barrier. |
| 8, 9 | GND1, GND2 | Isolated ground references - mandatory for maintaining >5000 VRMS creepage/clearance and preventing ground-loop coupling. |
| 10–15 | OUTF, OUTE, OUTD, OUTC, OUTB, OUTA | CMOS/LVCMOS outputs - all on secondary (VCC2/GND2) side; F-suffix ensures low-state default on fault or power loss. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Insulation Certification | Validated to DIN EN IEC 60747-17 (VDE 0884-17), UL 1577, CSA IEC 62368-1, CQC GB4943.1 - eliminates need for external safety capacitors in BMS designs. |
| Surge Immunity | 12.8 kV peak surge rating (oil test) - withstands lightning-induced transients in onboard chargers and DC/DC converters. |
| EMC Robustness | ±8 kV IEC 61000-4-2 contact ESD across barrier - prevents latch-up or data corruption during service port handling in EV service bays. |
| Low-Power Operation | 1.4 mA/channel @ 1 Mbps - extends runtime in always-on vehicle subsystems (e.g., battery monitoring during sleep mode). |
| Fail-Safe Output Logic | Default-low (F-suffix) behavior on input loss - forces safe shutdown state in motor control gate drivers and contactor supervision circuits. |
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 |
|---|---|---|---|
| ISO7761FQDWRQ1 | One reverse-direction channel (INF→OUTF); five forward channels - enables bidirectional control loop feedback (e.g., gate driver status return). | Suitable for applications requiring isolated feedback path (e.g., desaturation detection return in IGBT drivers). | Select when closed-loop fault reporting across isolation barrier is required; not drop-in due to altered pin function mapping. |
| ISO7762FQDWRQ1 | Two reverse-direction channels (INE, INF → OUTE, OUTF); four forward - supports dual feedback paths or redundant control signaling. | Used in ASIL-B/C redundancy schemes where independent fault channels improve diagnostic coverage. | Choose for higher diagnostic coverage in safety-critical subsystems; requires PCB layout revision due to different pin assignments. |
Compared with ISO7760FQDWRQ1, ISO7761FQDWRQ1 adds one reverse channel for feedback, while ISO7762FQDWRQ1 adds two - both increase design flexibility for fault reporting but require pinout-aware layout changes and do not share identical channel directionality.

FAQ
What is the isolation rating and certification basis for ISO7760FQDWRQ1?
ISO7760FQDWRQ1 provides 5000 VRMS reinforced isolation per UL 1577 and is certified to DIN EN IEC 60747-17 (VDE 0884-17), CSA IEC 62368-1, CQC GB4943.1, and TUV EN 62368-1. These certifications validate its use in high-voltage automotive subsystems such as battery packs and inverters where double insulation is mandated.
Does ISO7760FQDWRQ1 support level translation between different supply voltages?
Yes, ISO7760FQDWRQ1 supports independent 2.25V–5.5V supplies on each side (VCCI and VCCO), enabling seamless level translation - for example, interfacing a 3.3V microcontroller to a 5V gate driver without external translators. This is confirmed in Section 6.3 Recommended Operating Conditions of the datasheet.
What does the 'F' suffix in ISO7760FQDWRQ1 indicate?
The 'F' suffix in ISO7760FQDWRQ1 specifies default-low output behavior: when input power is lost or the input signal is invalid, all six outputs (OUTA–OUTF) drive low. This fail-safe feature is essential for safety-critical automotive functions like contactor control and gate driver enable/disable sequencing.
How does ISO7760FQDWRQ1 achieve high CMTI performance?
ISO7760FQDWRQ1 achieves ±100 kV/μs typical common-mode transient immunity through optimized capacitive SiO₂ barrier design, differential receiver architecture, and layout techniques that minimize coupling asymmetry. This performance is measured per Figure 7-3 in the datasheet and validated across temperature and supply variations.
Is ISO7760FQDWRQ1 pin-compatible with other ISO776x-Q1 variants?
No, ISO7760FQDWRQ1 is not pin-compatible with ISO7761FQDWRQ1 or ISO7762FQDWRQ1. While all share the same DW-16 package and supply pin locations (VCC1/VCC2, GND1/GND2), the input/output pin assignments differ significantly - e.g., INF is Pin 7 in ISO7760FQDWRQ1 but Pin 10 in ISO7761FQDWRQ1 - requiring unique PCB layouts.
