DS1232 Micro Monitor Chip IC

DS1232 Micro Monitor Chip IC

The DS1232 is a microprocessor supervisory (Micro Monitor) IC designed to improve system reliability by monitoring the power supply and the microcontroller’s operation. It provides power-on reset, power-fail reset, and watchdog timer functions in a single, compact device.

The DS1232 ensures that the microprocessor is always started in a known and stable state by generating a reset signal during power-up, power-down, or when the supply voltage drops below a safe level. It also includes an independent watchdog timer that resets the system if the software fails to operate correctly.
