Hi Bhuvaneswar,
We do not have an exact reference design that meets your request. However, the TIDA-00159 reference design shows one of our dual channel isolated gate drivers in a simple compact half-bridge configuration.
The TIDA-01605 reference design also is a good reference for a half-bridge configuration that shows driving high side FETs.
Although we do not currently have any reference designs for our new devices such as UCC21330-Q1, you can take a look through the rest of our isolated dual channel gate driver portfolio (UCC21520-Q1, UCC21530-Q1, UCC21540-Q1, UCC21222-Q1, UCC21220-Q1, etc..) to find reference designs that may be helpful in your design. These should all follow a similar application design and will be mostly applicable to UCC21330-Q1.
Hope this is helpful. Feel free to ask any additional questions below.

Hiroki
Hi Hiroki,
Thanks for sharing the reference designs. Are there any considerations that I need to consider for driving high side MOSFET's in battery applications compared to the reference design of simple compact half bridge configuration.

Hi Bhuvaneswar,
For simple standard drivers such as UCC21330-Q1, the gate driver surrounding circuitry should be very similar. If your application is for driving only high-side MOSFETs, an isolated supply would be necessary to driver the high-side MOSFETs.
Section 8 of the datasheet goes into details for the gate driver surrounding circuitry.
Hope this answers your question!

Hiroki
