Hello Harish,
There is an example schematic with MC3377x BCC and external MOSFETs available, but it is confidential requiring an NDA.
If your company has not signed the NDA with NXP yet, you can request it from:
https://www.nxp.com/support/support:SUPPORTHOME
If there is a valid NDA in place, please create a standard support ticket (case) and share your NDA number.
BR, Tomas
