ISO7762QDWQ1 Übersicht
A digital isolator is a semiconductor device that transfers logic signals between circuits while maintaining galvanic isolation, typically thousands of protection classes by using capacitive, inductive, or optical coupling across an internal dielectric. The ISO7762 product family belongs to the broader category of integrated isolators, interface ICs within the power management / isolation product taxonomy, line sensing and communication between high-voltage and low-voltage domains. In a multi-rail system, the isolator sits between a high-voltage gate driver or motor control stage and a low-voltage MCU/ASIC, breaking ground loops and protecting the low-voltage side from high-voltage transients, surges, and fault events. Compared to optocouplers, modern CMOS digital isolators offer faster data rates, lower propagation delay, lower power, better CMTI, and superior temperature and lifetime stability.
Key differentiating features of the ISO7762QDWQ1 include 100 Mbps signaling across all six channels with typical propagation delay of 11 ns (5 ns max skew), wide-input voltage tolerance of 2.25 V to 5.5 V on each side for cross-domain level translation, reinforced 5000 Vrms per UL 1577-1, and integrated robust EMC certification that simplifies system-level ESD/EFT/surge compliance testing. The device supports default low or high output on power loss via enable pin control, and is available in 16-pin SOIC wide-body and SSOP packages. Per TI datasheet, the supply current is typically 14 mA at 100 Mbps with 5 V supplies on both sides, and the device meets VDE 0884-11 basic and reinforced insulation.
The ISO7762QDWQ1 is most commonly used in industrial automation, factory automation, and process-control networks, hybrid and electric vehicle (HEV/EV) powertrain, charging station, and battery management systems (BMS), solar inverter and photovoltaic (PV) island, telecom data center power conversion and digital control interfaces, isolated SPI/UART/CAN/JTAG links, motor-control gate-drive isolation, and high-voltage medical instrumentation requiring 5000 Vrms reinforcement. The combination of 100 Mbps speed and 85 kV/us CMTI makes it ideal for driving SiC and IGBT gate drivers where high dv/dt transitions are routine.
When designing with the ISO7762QDWQ1, place 0.1 uF and 10 uF VCC bypass capacitors close to each supply pin, and verify that the VDE 0884-11 creepage/clearance and PCB layout rules meet your safety isolation rating. The default output state on power loss is determined by the EN pin setting; plan enable sequencing accordingly to avoid undefined logic during multi-rail power-up.

Wichtigste Unterscheidungsmerkmale
- Automotive-grade reinforced 5000 Vrms isolation with 100 Mbps speed (vs. ISO7742QDWQ1)
- Highest CMTI (85 kV/us min) in TI 6-channel automotive isolator family (vs. ISO7742QDWQ1)
- Wide-body SOIC package with 8 mm creepage for reinforced 800-V systems (vs. ISO7762QDBQ1)
Designhinweise
Estimated: Provide 0.1 uF ceramic bypass capacitors within 2 mm of each VCC1/VCC2 pin, and a 4.7 uF to 10 uF bulk capacitor on each supply rail. The ISO7762QDWQ1 draws approximately 14 mA at 100 Mbps with 5 V supply on both sides per TI datasheet; insufficient decoupling can cause data corruption at high CMTI events.
Maintain at least 8 mm of PCB-to-creepage between side-1 and side-2 copper per VDE 0884-11 reinforced insulation. Per TI datasheet, the SOIC wide-body (DWQ) package provides 8 mm of internal clearance, but PCB layout must not reduce this. Do not route any side-1 trace within 8 mm of any side-2 trace, including internal layer signals. A PCB cutout or moat under the device helps meet reinforced insulation clearance in dense layouts.
The 85 kV/us CMTI of the ISO7762QDWQ1 ensures reliable operation in high-dv/dt environments such as SiC and IGBT gate drivers. Per TI datasheet, slow input slew rates below 1 V/us may cause output instability; ensure the input signal has rise/fall times below 1 us or place an external RC network. For SPI/CAN FD applications, series termination at the isolator output reduces reflections and EMI.
Do not power side-1 (VCC1) and side-2 (VCC2) from the same supply if the two domains need galvanic isolation - both sides must be independently powered from isolated rails. Per TI datasheet, leave unused inputs tied to VCC or GND through 1 kohm to 10 kohm resistors. The EN pin logic level determines default output on power-up; verify sequencing matches your system requirements.
