The MAX824REXK+T is a highly integrated and advanced multi-function supervisor IC for personal computer and server system applications. It combines all the essential functions for system power management, including system voltage and temperature monitoring, reset, interrupt and shutdown, and power control.

The MAX824REXK+T is an advanced and feature-rich supervisor IC that provides digital control and monitoring of system voltages, temperature and other key parameters. It offers digital reset, interrupt and shutdown functions, as well as additional features like marginal power supply current monitoring and system voltage blanking. It can also be used for power control in digital power supplies and automotive and industrial applications.

The MAX824REXK+T is designed to provide reliable system monitoring and control. It employs a two-phase architecture to combine system voltage monitoring, temperature validation and system protection functions. By monitoring the supply voltage level, external VDD and/or core voltage, and temperature respectively, the MAX824REXK+T can provide robust system monitoring, reset and power management functions.

The MAX824REXK+T can perform the following tasks:

• System voltage monitoring – the supervisor uses the system voltage supply, core voltage and/or external VDD as inputs for digital system voltage monitoring.
• Temperature validation – the supervisor checks if the internal temperature is within the specified range, and issues an interrupt in case of temperature exceeding the limits.
• System reset/shutdown – the supervisor will reset or shutdown the system in case of overvoltage, undervoltage, overtemperature conditions or abnormal digital voltage levels.
• Power control – the supervisor can be used for power control in digital power supplies, automotive and industrial applications.
• Externally adjustable timers – the supervisor offers externally adjustable timers, allowing user-programmable response time and debounce.
• Marginal power supply current monitoring – the supervisor monitors the power supply current and can issue an interrupt to signal excessive current consumption due to fan lockup or other issues.

The MAX824REXK+T employs several protection features to prevent permanent damage due to abnormal voltage conditions. It contains a latch circuit that can be used to prevent the system from restarting during a fault condition. Additionally, the supervisor is capable of detecting and issuing an interrupt signal in case of excessive power supply current consumption and is capable of system voltage blanking.

In conclusion, the MAX824REXK+T is an advanced and feature-rich supervisor IC that provides essential functions for system power management. It is suitable for a wide range of applications, including digital power supplies, automotive and industrial applications. With its system voltage monitoring, temperature validation and system reset/shutdown features, the MAX824REXK+T ensures reliable system monitoring and control.
