PMIC (Power Management Integrated Circuit) supervisors provide a valuable tool for monitoring and controlling power supplies in todays advanced electronics. The CAT140089MWI-GT3 is one such IC, designed to provide complete circuit protection and monitoring for power supplies from a single IC. It is a highly versatile, integrated voltage supervisor featuring overvoltage protection, configurable Power-good (PG) output and programmable supply voltage monitor.

The CAT140089MWI-GT3 is a low power, single voltage supervisor with low quiescent current. This IC is specifically designed to be the companion of main power switches such as FETs or MOSFETS. It provides integrated voltage monitoring and protection features that work together to ensure reliable and safe operation. The voltage supervisor has an integrated voltage regulator and an overvoltage protection circuit that is powered by its own internal regulator, eliminating the need to externally supply an additional supply voltage.

The primary purpose of the CAT140089MWI-GT3 is to monitor the input voltage of a system. The CAT140089MWI-GT3 will output a logic HIGH signal when the input voltage reaches the undervoltage threshold or when the output voltage reaches the overvoltage threshold. The output logic LOW when the input voltage falls below the undervoltage threshold or when the output voltage falls below the overvoltage threshold. This output signal can be used as an indication of device power status to other components in the system.

The CAT140089MWI-GT3 also provides configurable power-good output statistics. The Power-good output can be used to monitor the input voltage rail and the output voltage rail of the system. The CAT140089MWI-GT3 is also capable of providing an indication of the quality of the system\'s power supply. The Power-good output can be configured to output a logic HIGH signal when the input voltage and output voltage are above the undervoltage and overvoltage threshold respectively.

The CAT140089MWI-GT3 also features a programmable supply voltage monitor. This feature allows the user to program the IC to monitor multiple supply rails and indicate which rail is providing power to the system. This feature can be used to alert when power is removed from specific rails and provide an indication of system power status.

Finally, the CAT140089MWI-GT3 also provides an array of integrated fault protection features. These features include undervoltage lockout (UVLO), overvoltage detection and protection, overcurrent protection, power-good circuit and hardware reset. These features provide reliable protection for the system\'s power supply, helping to ensure safe and reliable operation.

In summary, the CAT140089MWI-GT3 is an integrated voltage supervisor designed to provide complete circuit protection and monitoring for power supplies from a single IC. It features a low power, single voltage supervisor with low quiescent current, and provides overvoltage protection, configurable Power-good output and programmable supply voltage monitor. The CAT140089MWI-GT3 also offers an array of integrated fault protection features to further protect the power supply from potential damage, ensuring reliable and safe operation. This all-in-one IC is an important tool for ensuring the reliability and safety of power supplies in todays advanced electronics.
