The DS1233A EconoReset monitors two vital conditions for a microprocessor: power supply and externaloverride. A precision temperature-compensated reference and comparator circuit are used to monitor thestatus of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power failsignal 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 350ms to allow the power supply andprocessor to stabilize. The second function of the DS1233A is pushbutton reset control. The DS1233Adebounces a pushbutton closure and will generate a 350ms reset pulse upon release.
