19-3139; Rev 2; 9, 04 Nanopower P Supervisory Circuits with Manual Reset and Watchdog Timer General Description The MAX6854, MAX6855, MAX6856, MAX6858, MAX6860 MAX6869 ultra-low-current (170nA, typ) microprocessor ( P) supervisory circuits combine voltage monitoring, watchdog timer, and manual reset input functions in a 5pin SOT23 package. These devices assert a reset signal whenever the monitored voltage drops below the factorytrimmed reset threshold voltage, manual reset is asserted, or the
