The MAX16033–MAX16040 supervisory circuits reducethe complexity and number of components required forpower-supply monitoring and battery-control functionsin microprocessor (µP) systems. The devices significantlyimprove system reliability and accuracy comparedto other ICs or discrete components. TheMAX16033–MAX16040 provide µP reset, backup-batteryswitchover, power-fail warning, watchdog, andchip-enable gating features.The MAX16033–MAX16040 operate from supply voltagesup to 5.5V. The factory-set reset threshold voltageranges from 2.32V to 4.63V. The devices feature a manual-reset input (MAX16033/MAX16037), a watchdog timer input (MAX16034/MAX16038), a battery-on output (MAX16035/MAX16039), an auxiliary adjustable resetinput (MAX16036/MAX16040), and chip-enable gating(MAX16033–MAX16036). Each device includes a power-fail comparator and offers an active-low push-pull reset or an active-low open-drain reset.The MAX16033–MAX16040 are available in 2mm x 2mm, 8-pin or 10-pin µDFN packages and are fully specified from -40°C to +85°C.ApplicationsPortable/Battery-Powered EquipmentPOS EquipmentCritical µP/µC Power MonitoringSet-Top BoxesControllersComputersFax MachinesIndustrial ControlReal-Time ClocksIntelligent Instruments
