Details
The DS1818 EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize.FEATURES ● Automatically restarts a microprocessor after power failure ● Monitors pushbutton for external override ● Maintains reset for 150 ms after VCC 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 ● Low-cost TO-92 or space saving surface mount SOT-23 packages available ● Efficient open-drain output with internal 5.5 kΩ=pull-up resistor ● Operating temperature -40°C to +85°C
