DS1233-5+

The DS1233-5+ is a 5V EconoReset Monitor features automatically restarts microprocessor after power failure and maintains reset for 350ms after VCC returns to an in-tolerance condition or pushbutton released. The DS1233 EconoReset monitors two vital conditions for a microprocessor of power supply and external override. A precision temperature-compensated reference and comparator circuit are used to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal 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 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.
