FEATURES
§ Automatically restarts a microprocessor after
power failure
§ Maintains reset for 150ms after V
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
DESCRIPTION
The DS1815 EconoReset uses a precision temperature reference and comparator circuit to monitor the
status of the power supply (V
signal is generated which forces reset to the active state. When V
the reset signal is kept in the active state for approximately 150ms to allow the power supply and
processor to stabilize.
