Same package as TI alternatives but different pinout (vs ISO5852S)

Design Notes

For optimal performance, place the ADUM4222ARWZ close to the power switches to minimize gate loop inductance. Use separate ground planes for primary and secondary sides, and maintain proper creepage and clearance distances for the 5000 V rms isolation rating. Refer to the datasheet layout guidelines for recommended PCB patterns.

Ensure the secondary supply (VDD2) is adequately decoupled with a 1 uF ceramic capacitor placed close to the VDD2 and GND2 pins. The primary supply (VDD1) should also be decoupled with a 0.1 uF capacitor. This helps maintain stable operation and reduces noise coupling.

Do not exceed the absolute maximum ratings for VDD1 (6V) and VDD2 (20V). Also, ensure that the input signals (VIA, VIB) are within the specified input voltage range. Incorrect logic levels can cause malfunction or damage. Always verify the input configuration matches your control signals.
