DS1233A is a microprocessor monitor chip manufactured by Maxim Integrated (formerly Dallas Semiconductor).

The DS1233A is a microprocessor monitor chip manufactured by Maxim Integrated (formerly Dallas Semiconductor). Here are its key specifications:

  • Function: Monitors microprocessor activity and resets the system if software execution stalls.
  • Watchdog Timer: Features a programmable watchdog timer that can be set to timeouts of 150ms, 600ms, or 1.2s.
  • Manual Reset Input: Includes a manual reset pin for external reset triggering.
  • Power-On Reset: Generates a reset pulse upon power-up to ensure proper system initialization.
  • Voltage Monitoring: Monitors the 5V power supply and asserts reset if the voltage drops below a specified threshold (typically 4.75V).
  • Reset Output: Active-low reset output with a minimum pulse width of 250ms.
  • Operating Voltage: 5V ±10%.
  • Package: Available in an 8-pin DIP or SOIC package.
  • Temperature Range: Operates over the industrial temperature range of -40°C to +85°C.
  • Applications: Used in embedded systems, industrial controls, and other applications requiring reliable microprocessor supervision.
