UCC21550: UCC21550 - to Drive High side FET -ON Continuously

Part Number: UCC21550


        I want use UCC21550 for one of motor Drive application. On our application this Driver I.C. is used to Drive a High side MOSFET and a Low side FET. Load is connected between High side FET and Low side FET. Hence we have following Requirements:

1> Both High side and LOW side will be On at the same time . Hence dead Time needs to be disabled.

2> High side FET is required to be continuously on . Hence instead of bootstrap capacitor we will connect an isolated 12V Supply between VSSA and VDDA pins of the I.C. That is a Separate supply to continiously power the high side section. 

Please let me know if there will be any issue for above 2 points.
