ISO7760QDWRQ1 Présentation
A digital isolator is a semiconductor device that transfers logic signals across an isolation barrier using high-voltage capacitors or miniature transformers, while blocking DC and low-frequency noise between grounds. Digital isolators belong to the broader category of signal isolators and sit within signal-chain and interface ICs, replacing legacy optocouplers with 10x faster data rates, 1/10 the propagation delay, tighter channel-to-channel matching, and superior CMTI for noisy motor-drive and industrial environments.
Key features of the ISO7760QDWRQ1 include reinforced 5000 VRMS isolation (DW package) certified to UL 1577, VDE 0884-11, CSA, TUV and CQC, six unidirectional channels with default output low or high options, low power consumption of 1.3 mA per channel typical at 1 Mbps, and a wide supply range of 2.25 V to 5.5 V on both sides. The wide-body SOIC package provides the required 8 mm creepage and clearance for reinforced isolation.
The ISO776x-Q1 family uses TI's capacitive isolation technology with an SiO2 dielectric barrier, delivering >40-year projected lifetime at rated working voltage and robust EMC performance (low emissions, high immunity). On-chip ESD cells protect each pin against 4 kV HBM and 1 kV CDM discharges, reducing external protection component count.
Typical applications include isolated SPI/UART interfaces in EV traction inverters and BMS modules, isolated gate-drive signal paths for SiC/IGBT power stages, CAN/LIN transceivers in 48-V mild-hybrid systems, and industrial PLC analog/digital backplane isolation. Designers should leave the enable pin in a defined state (tied high or low via 4.7 kV presents at the pin) and place 0.1 uF VCC bypass capacitors as close as possible to each supply pin to meet emissions targets.

Applications typiques
ISO7760QDWRQ1 convient pour 7 applications: EV Traction Inverter Gate-Drive Isolation, Battery Management System (BMS) Communication Isolation, Industrial PLC Analog/Digital Backplane Isolation, Isolated SPI / UART Interface for Medical Devices, Solar Inverter Isolated Communication, Server PSU Isolated Feedback & Bias, Isolated CAN-FD Bus for Automotive Networks.
EV Traction Inverter Gate-Drive Isolation
The ISO7760QDWRQ1 provides reinforced 5000 VRMS isolation between the low-voltage MCU and high-voltage gate-driver stage in 400 V/800 V traction inverters. Six forward channels carry PWM, fault, and enable signals from control to SiC/IGBT drivers with 11 ns typical propagation delay, preserving switching-edge accuracy at high PWM frequencies. The 85 kV/us CMTI exceeds the dv/dt generated by 800 V SiC switches switching at 50 kV/us, preventing false triggering. AEC-Q100 Grade 1 qualification supports under-hood automotive environments from -40 C to +125 C.

Battery Management System (BMS) Communication Isolation
The ISO7760QDWRQ1 isolates the high-voltage battery monitor from the vehicle's low-voltage CAN network in 400 V/800 V BMS modules. Six forward channels carry cell-voltage sense, temperature, and balancing control signals with reinforced 5000 VRMS isolation meeting IEC 60747-17/VDE 0884-11. Low 1.3 mA per-channel quiescent current preserves pack standby time, while AEC-Q100 Grade 1 qualification supports automotive temperature ranges. The wide-body SOIC's 8 mm creepage satisfies reinforced isolation distances mandated across the high-voltage/low-voltage boundary.
Recommandé
Industrial PLC Analog/Digital Backplane Isolation
The ISO7760QDWRQ1 provides channel-dense reinforced isolation between industrial PLC backplanes and field-side I/O modules operating at 24 V/480 V. Six channels in a single SOIC-16W package reduce board area versus multiple optocouplers, while 100 Mbps data rate supports high-speed fieldbus protocols like Profinet and EtherCAT. The 5000 VRMS isolation withstands line-voltage transients on motor-control outputs, and VDE 0884-11 certification simplifies IEC 61131-2 compliance for industrial control cabinets.
Recommandé
Isolated SPI / UART Interface for Medical Devices
The ISO7760QDWRQ1 isolates SPI and UART communication between patient-connected circuits and host controllers in IEC 60601-1 medical equipment, where reinforced 5000 VRMS isolation provides two means of patient protection (MOPP). Six channels enable simultaneous isolation of clock, data, chip-select, and interrupt lines for ADC/DAC peripherals. Low propagation delay (11 ns typical) preserves SPI clock integrity up to 50 MHz, while capacitive SiO2 dielectric ensures >40-year insulation life for long-term implantable or bedside equipment reliability.
Recommandé
Solar Inverter Isolated Communication
The ISO7760QDWRQ1 isolates the DC-side MPPT controller from the AC-grid-connected inverter section in photovoltaic systems, providing reinforced 5000 VRMS isolation between high-voltage DC bus (up to 1500 V) and grid-tie electronics. Six forward channels carry switching PWM, sync, and telemetry signals with 85 kV/us CMTI tolerating fast-switching SiC MOSFET transients. AEC-Q100 Grade 1 temperature range supports outdoor enclosures in hot-climate solar farms, and UL 1577/VDE certifications accelerate grid-tie inverter certification cycles.
Recommandé
Server PSU Isolated Feedback & Bias
The ISO7760QDWRQ1 isolates primary-side switching controllers from secondary-side logic in 800 W/1500 W CRPS server power supplies. Six channels carry PWM feedback, enable, fault, and bias supply telemetry across the 1500 VDC isolation barrier. With 100 Mbps data rate, the part supports high-bandwidth digital-feedback loops used in advanced GaN-based totem-pole PFC stages, while AEC-Q100 Grade 1 reliability exceeds data-center thermal requirements. VDE 0884-11 and UL 1577 certifications simplify IEC 62368-1 audio/video/ICT equipment safety approval.
Recommandé
Isolated CAN-FD Bus for Automotive Networks
The ISO7760QDWRQ1 isolates CAN-FD transceiver bus lines between ECUs in 48 V mild-hybrid and zonal vehicle architectures. Six forward channels support isolated CAN-FD TX/RX, plus wake-up and fault signals for up to three transceiver nodes. 100 Mbps data rate exceeds CAN-FD's 5 Mbps requirement with substantial margin for future CAN-XL upgrades. Reinforced 5000 VRMS isolation and AEC-Q100 Grade 1 qualification make it ideal for combining 48 V bus isolation, in 12 V zonal modules.

- 85 kV/us minimum CMTI - best-in-class for SiC/IGBT gate-drive (vs ADuM160N (Analog Devices))
- 100 Mbps data rate across all six channels (vs ISO7760F-Q1 (1 Mbps))
Notes de conception
Place 0.1 uF low-ESR ceramic bypass capacitors (X7R or X5R dielectric) as close as possible to each VDD pin (pin 1 and pin 16) of the ISO7760QDWRQ1, ideally within 2 mm of the package. Add 1 uF to 10 uF bulk capacitors in parallel for low-impedance supply paths during fast load transients. Keep the isolation barrier (between pins 1-8 side-1 side and pins 9-16 side-2 side) clear of copper traces, vias, and PCB components to maintain 8 mm creepage per UL 1577.
Estimated: a 100 Mbps signal has a 10 ns unit interval, so channel-to-channel propagation delay matching (~2 ns) is critical to avoid inter-symbol skew. Do not place switching DC-DC nodes within 5 mm of the isolation barrier - their stray capacitance can degrade CMTI. Avoid routing high-dv/dt traces (gate-drive PWM) on inner layers crossing beneath the isolation barrier; use the barrier as a hard keep-out. Confirm that the enable pin (where present on other ISO77xx variants) is tied high or low, never floating.
Wide-body SOIC-16 (DW) provides 8 mm creepage and clearance for reinforced isolation per IEC 60747-17. The PCB land pattern should remove all solder mask and copper beneath the package body to maintain the isolation barrier integrity. For double-sided boards, do not place any copper (including ground planes) directly underneath the isolation barrier - a true absence-of-copper keep-out of at least 1 mm wider than the package body on all sides is required.
