1 M MICROCTRONIC-MARIN SA oltag tctor, High-Prcision scription Th is an ultra-low currnt voltag dtctor availabl in a larg varity of configurations and vry small packags for maximum flxibility in all nd-applications up to 5 C and using powr supplis btwn.5 and 5.5. This circuit monitors th supply voltag of any lctronic systm, and gnrats th appropriat rst signal without a dlay tim. Th thrshold dfins th minimum allowd voltag which guarants th good functionality of th systm. As long as stays abov th thrshold voltag, th output stays inactiv. If drops blow TH, th output gos activ. Th output is guarantd to b in th corrct stat for down to.8. Thr ar rst thrshold voltags starting as low as. and up to 4.6. Th faturs thr output typs: activ-low push-pull, activ-low opn-drain and activ-high push-pull. Small SC7 and SOT packags as wll as ultra-low supply currnt of.7μa mak th an idal choic for portabl and battry-opratd dvics. Typical Application Faturs Ultra-low supply currnt of.7μa ( =.)
