DS1814/DS1819 5V and 3.3V Micro Monitor
●The DS1814 5-Volt Micro Monitor and the DS1819 3.3V Micro Monitor monitor three vital conditions fora microprocessor: power supply, software execution, and external override. First, a precision temperature-compensated reference and comparator circuit monitor the status of V-CC. When an out-of-tolerance condition occurs, an internal power-fail signal is generated which forces the reset(s) to an active state.When V-CC returns to an in-tolerance condition, the reset signal is kept in the active state for a minimum of 140ms to allow the power supply and processor to stabilize.
■FEATURES
●Halts and restarts an out-of-control microprocessor
●Holds microprocessor in check during power transients
●Automatically restarts microprocessor after power failure
●Monitors pushbutton for external override
●Accurate 5%, 10%, or 20% (3V only) microprocessor power monitoring
●Eliminates the need for discrete components
●20% tolerance for use with 3.0V systems
●Pin- and function-compatible with the MAX823/24/25 products
●Low cost SOT-23-5 package
●Industrial temperature range: -40℃to +85℃
