This is the structure of FAN3100 gate driver IC:
(taken from its datasheet)
As you can see – there are two ouput switches: CMOS and BJT.
Why they put them both?

Paragraph 2 of the description says:
At the bottom of page 14 in the section *MillerDrive Gate Drive Technology" it goes on to explain:
The answer to "Who can tell me about Miller Plateau?" explains it thus:
The BJTs are able to get the output moving while the MOSFETs are ramping up. The MOSFETS can then provide the rail to rail voltage swing.
