Product details
Overview
ISO7710FQDWRQ1 from Texas Instruments is a reinforced single-channel digital isolator for automotive systems, delivering 100Mbps data rate, ±100kV/μs typical CMTI, and 5000VRMS isolation rating in DW-16 SOIC package. It features default-low output logic (F-suffix), 2.25V–5.5V dual-supply operation, and AEC-Q100 Grade 1 qualification (–40°C to 125°C ambient) for battery management and traction inverter interfaces.
For engineers reviewing the ISO7710FQDWRQ1 datasheet, ISO7710FQDWRQ1 pinout, ISO7710FQDWRQ1 application, or ISO7710FQDWRQ1 equivalent, this page delivers verified functional safety support, VDE-reinforced insulation compliance, propagation delay (11ns typ. at 5V), level translation capability, and automotive-grade EMC robustness - all specific to the ISO7710FQDWRQ1 variant with F-suffix and DW-16 package.
Technical Context
The ISO7710FQDWRQ1 implements an on-off keying (OOK) modulation scheme across a double capacitive SiO₂ isolation barrier, enabling high-speed signal transmission while suppressing radiated emissions. Its transmitter encodes logic states as presence or absence of a high-frequency carrier; the receiver performs envelope detection and signal conditioning before buffering the output.
This architecture delivers 12.8kV surge immunity and >30-year lifetime at 1500VRMS working voltage, with independent VCC1/VCC2 supplies supporting bidirectional level translation between 2.25V and 5.5V domains. The F-suffix variant asserts low output during input power loss, critical for fail-safe motor control gate drivers and BMS fault signaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100 Mbps maximum - supports high-speed CAN FD, SPI, and PWM feedback loops in EV powertrain control |
| Isolation Rating | 5000 VRMS (UL 1577), reinforced per VDE 0884-17 - enables safe interface between high-voltage traction inverters and low-voltage MCU domains |
| CMTI | ±100 kV/μs typical - maintains signal integrity during fast-switching IGBT/SiC gate driver transients in motor drives |
| Propagation Delay | 11 ns typical at 5V - ensures tight timing alignment for real-time current sensing and protection circuits |
| Supply Range | 2.25 V to 5.5 V per side - allows direct interfacing with 3.3V MCUs and 5V analog front-ends without level shifters |
| Default Output State | Low (F-suffix) - provides fail-safe deactivation of downstream power stages upon primary-side supply loss |
| Ambient Temp Range | –40°C to 125°C - qualified for under-hood and battery-pack mounting in hybrid/electric vehicles |
Pinout & Package
ISO7710FQDWRQ1 uses the wide-body 16-pin SOIC (DW-16) package with 10.30 mm × 10.30 mm footprint and 10.30 mm × 7.50 mm body size, optimized for creepage/clearance compliance in high-voltage automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Primary-side power supply | Supplies input buffer and transmitter; UVLO threshold 2.25V rising / 1.8V falling |
| VCC2 | Secondary-side power supply | Supplies receiver and output buffer; independent of VCC1 for galvanic isolation integrity |
| GND1 | Primary-side ground reference | Return path for VCC1 domain; electrically isolated from GND2 by SiO₂ barrier |
| GND2 | Secondary-side ground reference | Return path for VCC2 domain; enables noise-free signal coupling across isolation boundary |
| IN | Digital input signal | CMOS/LVCMOS-compatible input with 0.3×VCC1 to 0.7×VCC1 thresholds and 10 µA leakage |
| OUT | Digital output signal | Push-pull output with 4 mA drive strength at 5V; defaults low on VCC1 loss (F-suffix) |
| NC (Pins 2,5,6,8,10,11,12,15) | No-connect terminals | Unbonded pads; must remain unconnected to preserve isolation barrier integrity and certification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8610BD-B-IS | 3750 VRMS isolation rating (UL), 150 Mbps data rate, 5.5 ns propagation delay; no AEC-Q100 qualification | Targeted at industrial automation, not automotive safety-critical systems | Select only for non-automotive designs requiring higher speed and lower latency |
| ADUM110N0BRZ-RL7 | 3000 VRMS isolation (UL), 150 Mbps, 10 ns propagation delay; AEC-Q100 Grade 1 qualified but lacks VDE reinforcement | Approved for ASIL-B but not ASIL-D due to basic insulation classification | Use where cost sensitivity outweighs need for reinforced certification in mid-tier EV subsystems |
Compared with ISO7710FQDWRQ1, Si8610BD-B-IS offers higher speed but no automotive qualification, while ADUM110N0BRZ-RL7 matches temperature grade but lacks VDE-reinforced certification required for ASIL-D traction systems - making ISO7710FQDWRQ1 the only option meeting full automotive safety and isolation standards simultaneously.

FAQ
What does the 'F' suffix in ISO7710FQDWRQ1 indicate?
The 'F' suffix denotes a default-low output configuration: when VCC1 drops below its UVLO threshold (1.8V), the ISO7710FQDWRQ1 output transitions to and holds a logic-low state. This fail-safe behavior is essential for deactivating power stages in automotive safety-critical systems like traction inverters and battery disconnect units, and is confirmed in TI's ISO7710-Q1 datasheet Section 24.3.1 and Table 24-1.
Does ISO7710FQDWRQ1 support level translation between different supply voltages?
Yes, ISO7710FQDWRQ1 supports true bidirectional level translation between 2.25V and 5.5V on each side - VCC1 and VCC2 can operate independently at different voltages. This enables direct interfacing between 3.3V microcontrollers and 5V analog sensors or gate drivers without external level shifters, as specified in the Recommended Operating Conditions table (Section 8) and Features list of the ISO7710FQDWRQ1 datasheet.
What certifications apply specifically to the ISO7710FQDWRQ1 DW-16 package?
The ISO7710FQDWRQ1 in DW-16 package is certified for reinforced insulation per VDE 0884-17 (DIN EN IEC 60747-17), UL 1577 (5000 VRMS), IEC 62368-1 (800 VRMS working voltage), IEC 60601-1 (2 MOPP), and GB 4943.1. These certifications are explicitly tied to the DW-16 variant in TI's Safety-Related Certifications table (Section 12) and Insulation Specifications (Section 11).
How does ISO7710FQDWRQ1 achieve its ±100kV/μs CMTI performance?
ISO7710FQDWRQ1 achieves ±100kV/μs typical common-mode transient immunity through a combination of double capacitive SiO₂ isolation barrier design, on-chip signal conditioning, and advanced layout techniques that minimize coupling paths. This performance is measured per Figure 23-3 test circuit and confirmed in Electrical Characteristics tables (Sections 14–18) across all supply voltages - critical for noise immunity in high-dV/dt motor drive environments.
Is ISO7710FQDWRQ1 pin-compatible with other devices in the ISO77xx-Q1 family?
No - ISO7710FQDWRQ1 is not pin-compatible with other ISO77xx-Q1 variants. While all share the DW-16 package outline, pin functions differ across channel count and direction configurations (e.g., ISO7720-Q1 has two channels and different pin assignments). Pin compatibility is only guaranteed within identical part numbers; the ISO7710FQDWRQ1 pinout is unique to its single-channel, forward-only, F-suffix configuration as shown in Figure 4-1 and Table 4-1 of the datasheet.
