FEATURES
§ Automatically restarts microprocessor after
§ Monitors pushbutton for external override
§ Internal circuitry debounces pushbutton
§ Maintains reset for 350ms after V
§ Accurate 5%, 10%, or 15% microprocessor
§ Reduces need for discrete components
§ Precision temperature-compensated voltage
§ Low-cost TO-92 package or surface-mount
§ Internal 5kW pull-up resistor
§ Operating temperature of -40°C to +85°C
DESCRIPTION
The DS1233 EconoReset monitors two vital conditions for a microprocessor: power supply and external
override. A precision temperature-compensated reference and comparator circuit are used 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 350ms to allow the power supply and
processor to stabilize. The second function of the DS1233 is pushbutton reset control. The DS1233
debounces a pushbutton closure and will generate a 350ms reset pulse upon release.
OPERATION — POWER MONITOR
The DS1233 provides the functions of detecting out-of-tolerance power supply conditions and warning a
processor-based system of impending power failure. When V
defined by the tolerance of the part selected, the
for approximately 350ms after the power supply has reached the selected tolerance. This allows the power
