- 6 isolated digital channels supporting up to 150 Mbps for high-speed signal crossing across isolation barriers
- AEC-Q100 automotive-qualified operation ensuring reliability across the extended temperature range
- 2.25 V to 5.5 V supply range on both sides enabling mixed 3.3 V and 5 V system integration
- 4 kV isolation rating protecting sensitive MCU logic from high-voltage power stage transients
- Robust EMC design meeting IEC 61000-4-4 EFT and IEC 61000-4-5 surge immunity requirements
What is ISO7761QDWQ1 used for?
ISO7761QDWQ1 is targeted at automotive electric vehicle inverters and on-board chargers requiring 6-channel isolation between the high-voltage power stage and low-voltage control MCU. Its 150 Mbps channel speed and 4 kV isolation barrier also suit industrial motor drive gate drive interfaces, where fast PWM signals must cross a galvanic isolation boundary without propagation distortion. Industrial safety PLCs and 48 V battery management systems benefit from its dual-supply flexibility and automotive-grade qualification.

Frequently Asked Questions
How many isolated channels does ISO7761QDWQ1 provide and at what maximum data rate?
ISO7761QDWQ1 provides 6 isolated digital channels, each capable of operating at up to 150 Mbps. This channel count and speed make it suitable for simultaneously isolating PWM, enable, fault, and status signals between a gate driver and a microcontroller in a 3-phase inverter without requiring multiple discrete optocoupler chains.
What isolation voltage does ISO7761QDWQ1 provide and which automotive systems require this level?
ISO7761QDWQ1 provides a 4 kV isolation barrier between the two signal domains, meeting the creepage and clearance requirements for automotive high-voltage EV inverters operating from 400 V or 800 V battery stacks. This isolation level also satisfies IEC 61010-1 reinforced insulation needs in industrial motor controllers with 480 V AC mains.
Can ISO7761QDWQ1 interface directly between a 3.3 V MCU and a 5 V gate driver without external level shifters?
Yes, ISO7761QDWQ1 accepts 2.25 V to 5.5 V independently on each side, so a 3.3 V microcontroller and a 5 V gate driver can communicate directly through the isolation barrier with no external level-shifting circuitry. This dual-supply flexibility reduces component count and simplifies board layout in mixed-voltage automotive and industrial drive systems.
How does ISO7761QDWQ1 compare to optocoupler-based isolation in EV inverter gate drive designs?
ISO7761QDWQ1 delivers 150 Mbps propagation with approximately 10 ns channel-to-channel skew, compared to optocouplers which typically limit bandwidth below 10 Mbps with much larger propagation delays. The digital isolator also eliminates LED current drive circuitry, reducing BOM complexity and enabling consistent timing margins in high-frequency PWM gate drive paths at switching frequencies above 50 kHz.
