The DS1830 Reset Sequencer monitors the power supply for an in-tolerance condition and the pushbutton reset input for a manual reset. First a precision temperature-compensated reference and comparator circuit monitors the status of the power supply and when an out-of-tolerance condition is detected, an internal power fail signal is generated that forces the reset lines to go to an active state. If the power supply returns to an in-tolerance condition, reset 1 will release followed by reset 2 and finally reset 3. Sequencing of resets allows for systems to power-up in an orderly manner providing superior reliability.ApplicationsAutomated Test Equipment (ATE)Automatic Utility Meter ReadingBuilding Security/Remote CamerasCable ModemsCell Phone Base Stations Cell PhonesComputers: Desktop, Workstation, ServerCordless PhonesDigital Television (Receivers, Set-Top Boxes)End EquipmentGlobal Positioning Systems (GPS)Modems (Analog, ISDN, DSL)Network Hubs, Switches, RoutersNotebook ComputersPagersPalmtops, Handy Terminals (incl. barcode)Pen Entry Palmtops, PDAs and OrganizersPoint-of-Sale TerminalsPortable Patient Monitoring/Drug DeliveryPrinters and FaxesTest and Measurement Equipment
