Key Differentiators
- iCoupler technology provides superior performance over optocouplers (vs Optocoupler-based isolators)
- High CMTI of 25kV/µs (vs ISO7721DR (100kV/µs))
- Wide supply voltage range (vs SI8621BB-B-ISR (2.5V to 5.5V))
Design Notes
Place 0.1µF bypass capacitors close to VDD1 and VDD2 pins to ensure stable operation. Use a 10µF capacitor in parallel for bulk decoupling. Keep the isolation barrier clear of copper traces to maintain isolation performance.
Maintain proper creepage and clearance distances between the two sides of the isolation barrier as per the datasheet. For 2500Vrms isolation, a minimum of 4mm creepage is recommended. Avoid routing high-voltage traces near the isolator.
Do not exceed the absolute maximum ratings for supply voltage. Ensure VDD1 is within 3.0V to 3.6V and VDD2 within 4.5V to 5.5V. Incorrect supply voltages can cause malfunction or damage. Also, verify that the data rate does not exceed 1Mbps to avoid signal integrity issues.
Compliance Information
RoHS compliant per distributor data. Not AEC-Q100 qualified; use ADUM1201WURZ-RL7 for automotive.
