3.3V EconoReset with Push-Pull Output

The DS1815 EconoReset uses a precision temperature 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 150ms to allow the power supply and processor to stabilize.

* Automatically restarts a microprocessor after power failure

* Maintains reset for 150ms 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

* Push-pull output for low current operation

* Operating temperature -40°C to +85°C
