  We perform an exclusive study on the Feebly Interacting Massive Particle
(FIMP) dark matter candidate in an extended hyperchargeless ($Y=0$) Higgs
triplet model. The additional $Z_2$ odd neutral fermion singlet plays the role
of dark matter with support from two other vector-like fermion doublets. The
mixing between the neutral component of a doublet and singlet fermions controls
the current relic density through the Freeze-in mechanism, whereas the
additional doublet fermion helps to get the neutrino mass and mixing angles. We
obtain a broad region of the parameter spaces satisfying the current relic
density and neutrino mass and mixing angles.
