Supersymmetry is one of the most motivated Standard Model extensions. Despite the search during the LHC Run I, there is no evidence supporting this theory. LHC is performing a second data taking with a higher center-of-mass energy, providing a great occasion for the search of beyond the Standard Model physics. New results obtained with the 2015-2016 ATLAS detector data will be presented. The direct production of electroweakinos, with leptons and missing transverse momentum in the final state, is considered. A good sensitivity is obtained in the signal region for supersymmetric particles masses beyond the Run 1 limits.
