The MAX794CSE+T is a Power Management Integrated Circuit (PMIC) belonging to the Supervisors category. It operationally monitors voltage levels to ensure proper power output and regulated power conditions in a variety of applications. These Supervisors PMICs provide continuous system and device status data concerning output power levels, regulator power, and faults. MAX794CSE+T guarantees voltage regulation under varying loads, temperature and input voltage conditions, out of the box.The MAX794CSE+T itself is a 3-V to 5.5-V microprocessor (µP)-supervisory circuit with a power-on reset (POR) and pushbutton reset. Its reset feature can be adjusted from 1.1 V to 1.6 V using an external resistor and it allows all of the standard power supply outputs to fall, allowing recovery without system interference.This PMIC Supervisors device has two main components, the main power supervisor, Dual Monitor MAX77421 (MAX77421), and the Body Bias Switcher MAX15000K (MAX15000K). The MAX77421 passes the centralized supervisor signals which are generated by monitoring the system\'s Voltages and the battery input to the microcontroller. The MAX15000K controls the body bias switcher, the on/off power switching, the system supply voltage and the external inductor and current limiting circuit.The MAX77421 monitors the input voltage and temperature conditions, while providing on-chip PMIC status information such as power-on reset (POR), low-voltage detect (LVD), and over-temperature detect. It has a wide input voltage range and provides up to long 4ms reset timing for applications with long debounce and reset requirements.The MAX15000K is responsible for controlling the body bias switcher. Its turn-on and turn-off timings are adjustable, allowing for the power delivery to be optimized according to the system\'s temperature and loading requirements. Its on/off power switching feature reduces power consumption in static power-down applications as well as provides power delivery in wake-up applications. Additionally, it allows for real-time monitoring of the system supply voltage, allowing for a safe power delivery at extreme temperature conditions.The MAX794CSE+T PMIC Supervisors works by regulating and monitoring the system\'s supply voltages, input voltages and temperatures. It ensures that the system\'s supply voltage is stable and within the specified limits, and if there are problems with the system, it will notify the host processor and provide a safe system reset.The MAX794CSE+T has been designed to be used in industrial and medical applications where power supply and temperature regulation are essential. The device\'s combination of dual monitor and body bias switcher control make it ideal for such applications. It is also a great choice when power consumption needs to be kept low and fault protection needs to be reliable. The MAX794CSE+T is a perfect choice for embedded systems where extreme-temperature protection and advanced system control are required.
