The MAX823SEUK+ is an integrated circuit (IC) component primarily used in the field of electrical and electronic engineering. It is a supervisory circuit with a watchdog timer and a manual reset input. This IC is manufactured by Maxim Integrated and is specifically designed to monitor the power supply voltage levels in microcontroller-based systems. It offers essential features that help ensure the reliable and safe operation of the system.
One of the key features of the MAX823SEUK+ is its ability to monitor the power supply voltage. It can track the voltage level and provide a reset signal if it falls below or rises above a certain threshold. This ensures that the microcontroller and other components in the system receive a stable and appropriate supply voltage, thereby preventing malfunctions or damage due to overvoltage or undervoltage conditions. The threshold voltages for under-voltage and overvoltage detection can be externally programmed.
Another important feature of this IC is its built-in watchdog timer. The watchdog timer is designed to detect and recover from software failures or system lock-ups. It requires periodic triggering to reset a dedicated counter, and if the counter is not reset within a predefined time interval, the watchdog timer will generate a reset signal. This helps in preventing the system from getting stuck in an undesired state and enhances its overall reliability.
The MAX823SEUK+ also incorporates a manual reset input, which allows an external signal or a push-button switch to initiate a system reset
