Product details
Overview
ISO6763FQDWRQ1 from Texas Instruments is a six-channel automotive-grade reinforced digital isolator with 50 Mbps data rate, 5000 VRMS isolation rating, ±150 kV/μs CMTI, and dual supply operation (1.71–1.89 V or 2.25–5.5 V per side). It features default-low output logic (F-suffix), 11 ns typical propagation delay, and is qualified to AEC-Q100 Grade 1 (–40°C to +125°C ambient) for use in EV battery management and inverter control systems.
For engineers reviewing the ISO6763FQDWRQ1 datasheet, ISO6763FQDWRQ1 pinout, ISO6763FQDWRQ1 application, or ISO6763FQDWRQ1 equivalent, key selection factors include its F-suffix default-low output behavior, 16-pin wide-SOIC package with asymmetric channel direction (4 forward, 2 reverse), robust VDA320 and UL/VDE/IEC safety certifications, and 1.71–5.5 V level translation capability across isolated domains.
Technical Context
The ISO6763FQDWRQ1 implements TI's double capacitive SiO₂ insulation barrier to achieve reinforced isolation up to 5000 VRMS and 10 kV surge immunity. Its channel configuration-four forward (INA→OUTA, INB→OUTB, INC→OUTC, IND→OUTD) and two reverse (INE←OUTE, INF←OUTF)-enables bidirectional signal routing across isolation boundaries without external logic inversion.
It supports independent 1.71–1.89 V or 2.25–5.5 V supplies on each side, enabling direct interfacing with low-voltage microcontrollers and higher-voltage gate drivers. The device meets system-level ESD, EFT, and emissions requirements per VDA320 and includes built-in UVLO detection with 1.53 V rising / 1.41 V falling thresholds per supply rail.
Key Specifications

FAQ
What does the 'F' suffix in ISO6763FQDWRQ1 indicate?
The 'F' suffix denotes default-low output behavior: when input power is lost or signals are invalid, all six output channels (OUTA–OUTF) assert logic low. This fail-safe state prevents unintended activation of downstream power devices in ISO6763FQDWRQ1-based motor control or BMS circuits, aligning with ISO 26262 ASIL-B safety goals.
How is the channel direction configured in ISO6763FQDWRQ1?
ISO6763FQDWRQ1 has four forward channels (INA→OUTA, INB→OUTB, INC→OUTC, IND→OUTD) and two reverse channels (INE←OUTE, INF←OUTF). This fixed pinout eliminates external inverters in closed-loop systems-for example, using OUTE/OUTF to return current-sense data while driving PWM via OUTA–OUTD.
Does ISO6763FQDWRQ1 support 1.8 V operation on both sides simultaneously?
Yes. ISO6763FQDWRQ1 supports 1.71–1.89 V on VCC1 and VCC2 concurrently, enabling ultra-low-power interfaces with 1.8 V MCUs and sensors. At this supply, propagation delay remains ≤15 ns and CMTI exceeds 100 kV/μs-verified per AEC-Q100 stress testing across –40°C to +125°C.
What safety certifications apply to ISO6763FQDWRQ1?
ISO6763FQDWRQ1 holds DIN EN IEC 60747-17 (VDE 0884-17), UL 1577 (5000 VRMS), IEC 62368-1, IEC 61010-1, IEC 60601-1, and GB 4943.1 certifications. It is rated for 600 VRMS reinforced insulation and 2 MOPP per medical standards-validated for EV battery packs, OBCs, and inverters per VDA320.
Can ISO6763FQDWRQ1 replace older TI isolators like ISO7763FQDWRQ1?
Yes-ISO6763FQDWRQ1 is a pin-to-pin upgrade to ISO7763FQDWRQ1 with identical DW-16 package, pinout, and footprint. It improves CMTI (±150 kV/μs vs. ±100 kV/μs), adds VDA320 compliance, and extends lifetime assurance to 30 years at 1500 VRMS-without requiring PCB or firmware changes.
