Part # Aliases
90-1810R+W05
FEATURES
§ Automatically restarts a microprocessor after
§ Maintains reset for 150 ms after V
§ Reduces need for discrete components
§ Precision temperature-compensated voltage
§ Low-cost TO-92 or space saving surface
§ Push-Pull output for low current operation
§ Operating temperature -40°C to +85°C
DESCRIPTION
The DS1810 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 150 ms to allow the power supply and
processor to stabilize.
