Data Sheet
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
power-fail signal is generated which forces reset to the active state. When V
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.
