The S-80142CLPF-JI3TFG is an example of a PMIC (Power Management Integrated Circuit). This specific form of IC consists of supervisors, analogical integrated circuits, and operational amplifiers. This IC is specifically a supervisor, a type of PMIC, and as such its main purpose is to protect the power source in circuitry. These ICs, supervisors, contain a range of features and functions, providing protection against overvoltage and undervoltage, but these devices can also provide monitoring of the power state and be used to prevent overcurrent in the circuitry. S-80142CLPF-JI3TFG supervisors are used most commonly in automotive and industrial applications, because of their high degree of reliability and safety.

PMIC supervisors, such as the S-80142CLPF-JI3TFG, are composed of a number of components and functions that provide protection or monitoring of the power source in the system. The voltage supervisor is the heart of the PMIC and its purpose is to monitor the system\'s power rail. It does this by comparing the actual voltage to the preset limits within the supervisor. The supervisor will then issue a level-check or reset signal if the voltage within the circuit is outside the specified limits. The voltage supervisors also allow for reset thresholds to be changed depending on the application. Additionally, the supervisors can be configured to be active-low or active-high, meaning they can trigger a reset signal when the voltage as either above or below its specified limit.

The PMIC supervisors may additionally contain other components and features, such as an under-voltage lockout, over voltage sequence detector, programmable waiting time, and a fault flag. The under-voltage lockout feature will protect the system from unstable inputs or when overvoltages of the system\'s power rail occur. This feature will reset the circuit if the power rail falls below the minimum voltage threshold, ensuring stability is maintained. The overvoltage detector can determine the level of input voltage, allowing the circuit to shut down if the power rail exceeds the specified thresholds.

The programmable waiting time allows the circuit to wait for a specified amount of reset before resetting itself. This allows data to be retained within the circuit, eliminating the need to reset memory or other components in the system. The fault flag is an alarm of sorts that is triggered when an over voltage, under voltage, or short-circuit condition is detected. This feature can be used to alert the user to any power irregularities.

This type of IC provides a number of safety functions and monitoring of the power state in a system and the S-80142CLPF-JI3TFG supervisor is designed specifically for the automotive and industrial sectors of electronics. The supervisor provides protection and monitoring for a wide range of input voltages, ensuring the stability and reliability of the system. As such it is an ideal choice for applications that require a high degree of safety and robustness with regard to the power supply.
