Product details

Six-channel SPI isolator rated for 5000 Vrms — what that means on the bench

The TI ISO6763QDWRQ1 is a 6-channel, unidirectional digital isolator built around capacitive coupling, designed to pass SPI buses across a galvanic isolation barrier. The 5000 Vrms isolation voltage is the headline number — that's a reinforced-grade barrier for applications where a fault on the high-voltage side must not reach the low-voltage controller. Common-mode transient immunity of 100 kV/µs keeps the data path clean when a motor drive or inverter switches at high dV/dt; a lower CMTI part would glitch and lose bits under those conditions.

No isolated power on board — plan the secondary-side rail

This part does not include an integrated DC-DC converter; isolated power is marked as 'No' in the spec. That means each side of the isolation barrier needs its own local supply rail.

Frequently asked questions

Is ISO6763QDWRQ1 automotive grade AEC-Q100 qualified?

Yes, the ISO6763QDWRQ1 is AEC-Q100 qualified and rated for an operating temperature range of -40°C to 125°C, making it suitable for automotive under-hood and other harsh environments.

Does ISO6763QDWRQ1 require external isolated power?

Yes, this isolator does not include an integrated isolated power supply. Side 1 requires a 1.71 V to 1.89 V rail, and Side 2 accepts 2.25 V to 5.5 V. You will need separate isolated supplies for each side of the barrier.

What are the equivalent or replacement parts for ISO6763QDWRQ1?

Within the same ISO676x-Q1 family, the ISO6762QDWRQ1 (4/2 input/output split) is a pin-compatible functional alternative if your signal direction requirements differ. All variants share the same 50 Mbps data rate, 5000 Vrms isolation, and 100 kV/µs CMTI.

How many channels does ISO6763QDWRQ1 have?

The ISO6763QDWRQ1 has 6 unidirectional channels arranged as 3 inputs on Side 1 and 3 inputs on Side 2, allowing bidirectional SPI communication with three chip-select or control lines.
