PMIC - Supervisors are a type of integrated circuit which provide protection, monitoring, and control functions for electronic devices such as computers, cell phones, and other aerospace/defense applications. The S-1000C40-M5T1G is a member of this class of circuits and is designed to provide a 5V detection circuit with both dual threshold and manual reset capability. The circuit provides two basic functions: threshold detection and manual reset. Threshold detection is used to detect a specified voltage difference between two compared voltages. The manual reset function allows for the user to reset the chip if the voltage difference exceeds a predetermined threshold without having to power cycle the device.

The S-1000C40-M5T1G is designed for use in military/aerospace use and commercial applications. In military/aerospace applications, these supervisors are used to keep critical systems running reliably and securely, protecting against unexpected shutdown due to an overvoltage, undervoltage, overcurrent or ESD events. Commercially, the circuits are used in consumer electronics such as computers, phones, and other digital devices to provide voltage protection and increase device reliability.

The S-1000C40-M5T1G is specifically designed to provide 5V overvoltage, undervoltage, overcurrent and ESD monitoring with dual threshold and manual reset capability. The 5V output voltage is provided by an internal regulator circuit which allows for variation in the input voltage supply. The two thresholds supported by the circuit are 3.55V and 4.26V, with a minimum reset voltage of 1.53V. The overvoltage and undervoltage protection are provided by a voltage comparator with hysteresis, and the overcurrent protection is provided by a precision current sensing circuit that monitors the output current.

The chip also has ESD protection which is provided by an integrated diode coupled with a resistive load. This resistive element reduces the ESD stress to the integrated circuit and protects the chip from ESD events. The diode ensures that the ESD pulse is quickly discharged when the pulse is over. The manual reset feature allows for the user to reset the chip if the voltage difference exceeds the predetermined threshold without needing to power cycle the device.

The S-1000C40-M5T1G is an effective solution for overvoltage, undervoltage, overcurrent and ESD protection in a variety of applications, including military/aerospace, consumer electronic, and commercial applications. The dual threshold and manual reset features allow for effective and reliable voltage regulation, while the integrated ESD protection ensures the reliability of the circuit.
