ADuM4223 Half Bridge Negative Bias

I am planning to use the ADuM4223 isolated MOSFET driver in boot strapped half bridge configuration, with three half bridges for driving a three phase motor. I would like to negative bias the MOSFET gates to avoid spurious turn-ons due to noisy ground. Does ADuM4223 support driving the gate below source voltage?


I would really appreciate if you can point me towards any documents explaining this application.
