DS1817 Active High 3.3V EconoReset
■The DS1817 EconoReset uses a precision temperature reference and comparator circuit to monitor thestatus of the power supply (V-CC). When an out-of-tolerance condition is detected, an internal power-failsignal is generated which forces reset to the active state. When V-CC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150 ms to allow the power supply andprocessor to stabilize.
●FEATURES
■Automatically restarts a microprocessor after power failure
■Maintains reset for 150 ms after V-CC returns to an in-tolerance condition
■Reduces need for discrete components
■Precision temperature-compensated voltage reference and voltage sensor
■Accurate 5%, 10% or 20% power monitoring
■20% tolerance for use with 3.0-volt systems
■Low-cost TO-92 or space saving surface mount SOT-23 packages available
■Push-pull active high output Operating temperature -40°C to +85°C
