We report on the results of INTEGRAL observations of the neutron star low mass X-ray binary SAX J1810.8-2609 during its latest active phase in August 2007. The current outburst is the first one since 1998 and the derived luminosity is 1.1 − 2.6 × 10 36 erg s −1 in the 20-100 keV energy range. This low outburst luminosity and the long-term time-average accretion rate of ∼ 5 × 10 −12 M ⊙ yr −1 suggest that SAX J1810.8-2609 is a faint soft X-ray transient. During the flux increase, spectra are consistent with a thermal Comptonization model with a temperature plasma of kT e ∼ 23-30 keV and an optical depth of τ ∼ 1.2-1.5, independent from luminosity of the system. This is a typical low hard spectral state for which the X-ray emission is attributed to the upscattering of soft seed photons by a hot, optically thin electron plasma. During the decay, spectra have a different shape, the high energy tail being compatible with a single power law. This confirm similar behavior observed by BeppoSAX during the previous outburst, with absence of visible cutoff in the hard X-ray spectrum. INTEGRAL/JEM-X instrument observed four X-ray bursts in Fall 2007. The first one has the highest peak flux (≈ 3.5 Crab in 3-25 keV) giving an upper limit to the distance of the source of about 5.7 kpc, for a L Edd ≈ 3.8 × 10 38 erg s −1 . The observed recurrence time of ∼1.2 days and the ratio of the total energy 1 INTEGRAL is an ESA project with instruments and science data center funded by ESA member states (especially the PI countries:
