DS1233AZ-10 Product Details

The DS1233AZ-10 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 (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 DS1233AZ-10 is pushbutton reset control. The DS1233AZ-10 debounces a pushbutton closure and will generate a 350ms reset pulse upon release.


  • Automatically restarts microprocessor after power failure
  • Monitors pushbutton for external override
  • Internal circuitry debounces pushbutton switch
  • Maintains reset for 350ms after VCC returns to an in-tolerance condition or pushbutton released
  • Accurate 5%, 10%, or 15% microprocessor 5V power supply monitoring
  • Reduces need for discrete components
  • Precision temperature-compensated voltage reference and voltage sensor
  • Low-cost TO-92 package or surface-mount SOT-223 package
  • Internal 5kΩpull-up resistor
  • Operating temperature of -40°C to +85°C
