Hi Naveen,
To be able to download the MC33665A full datasheet and other confidential documents you need to have a valid NDA (Non Disclosure Agreement) and you need to be registered on the nxp.com page. If you do not have the valid NDA yet, please request it here. After the process you can download the datasheet from the MC33665A product page under the secure files.
BRs, Tomas
