The MAX791CSE+T is a type of PMIC - Supervisors. It is a general-purpose supervisor IC primarily used to monitor and reset microcontroller-based systems. It provides excellent supply current monitoring as well as a Watchdog Timer/Reset signal to reset the system microcontroller in the event of a violation. This allows for fast and accurate system reset and recovery.The MAX791CSE+T operates as follows: when a valid power supply is applied, it is charged by two resistors connected at either the input or output pin. When the voltage at the input or output pin reaches a predetermined level, the IC is reset and the Watchdog Timer starts counting. When the timer count reaches its limit, a reset signal is sent to the microcontroller and the count is reset. In this way, the IC ensures the microcontroller is reset and recovers from any errors or out of range status.The MAX791CSE+T offers several features that make it optimal for use in microcontroller-based applications. It features an integral voltage detector with adjustable voltage level settings, an interrupt and reset terminals to reset the microcontroller when needed, a programmable reset window, and a programmable Watchdog Timer. Additionally, it has an on-chip low voltage detection circuit and a brown-out reset circuit, both of which are ideal for use in mobile systems.The MAX791CSE+T also offers a wide range of protection features for use in high-reliability applications, such as over-voltage protection, under-voltage protection, over-temperature protection, and over-current protection. Additionally, it has a built-in temperature compensated watchdog and power-on reset functions. This ensures that the system remains stable, even in extreme temperature ranges.The MAX791CSE+T is a versatile device suitable for use in a wide range of applications. In mobile systems, it can be used to monitor the power supply voltage and reset the system if the voltage drops below a specified threshold. In industrial automation systems, it can be used to detect a variety of faults, including voltage and current deviations, and reset the system in the event of any such occurrence. The MAX791CSE+T is also used in medical, automotive and robotics applications.In conclusion, the MAX791CSE+T is a versatile and reliable PMIC - Supervisors, offering a host of features that make it suitable for use in a wide range of applications. It provides excellent supply current monitoring as well as a Watchdog Timer/Reset signal to reset the system microcontroller in the event of a violation. Additionally, it has an integrated voltage detector, interrupt and reset terminals, a programmable reset window, and a programmable Watchdog Timer, making it a great choice for monitoring and resetting microcontroller-based systems.
