Power Management Integrated Circuits (PMICs) are integrated circuits (ICs) that are mainly used to manage the power of an electronic system. PMICs allow electronic devices to safely and efficiently manage power at the board level, optimizing current and voltage levels for both battery-powered and mains-powered operation. PMICs provide power-path management, which ensures that power is routed to the necessary places when needed. They also offer non linear compensation, which handles the dynamic output voltage power of the system. The LTC2960IDC-4 is a kind of PMIC, specifically classified as a supervisor.

Supervisors, such as the LTC2960IDC-4, are in-system voltage monitors designed to monitor and report power-system conditions. They include over-temperature, undervoltage, and overvoltage indications, with configurable reset or interrupt logic. The LTC2960IDC-4 is a single-phase digital supervisor with five trim inputs providing up to 0.5% tolerance accuracy. It includes an integrated thermal disconnect and can monitor four power-system supply rails with three additional inputs for miscellaneous monitoring. It provides digital signal output to alert the system if any of the monitored rails go below or above pre-set thresholds.

The LTC2960IDC-4 is suitable for a wide range of applications, such as automotive, consumer, industrial, security, and communications. It can be used in battery-powered applications such as portable consumer electronics, tablet computers, and wearable devices, where it helps to ensure that the system\'s power voltage does not go out of the range determined by the battery. It can also be used in wireless or wired communications systems to detect faults and prevent system shutdowns, or in industrial applications for power system monitoring and fault detection.

The LTC2960IDC-4 offers flexibility for many types of power systems. It can be programmed by connecting to the trim pins, using the trim pins as a resistive divider or a voltage reference depending on the power requirements of the application. It also comes with three additional user-configurable inputs, allowing it to monitor miscellaneous signals, including line state, battery status, and push-button status via an external pull-up resistor, allowing it to detect changes in push-button states, line states, and battery voltage.

The LTC2960IDC-4 operates on a wide supply range, from 4.65V to 17V, and can supply up to 200mA of current via its open-drain outputs. It includes an integrated temperature sensor, which can detect temperatures between -40 degrees Celsius and 150 degrees Celsius, and it can be used to alert the system of thermal overloads. It also has a wide range of reset or interrupt delays for maximum flexibility in setting thresholds for over- or undervoltage and temperature.

The LTC2960IDC-4 also has hysteresis and voltage loop control, which provides flexibility for configuring the voltage range threshold at which it will reset or trigger an interrupt signal. It is designed to operate over the entire specification range from -40 degrees Celsius to 150 degrees Celsius without the need for external components.

The LTC2960IDC-4 can also be used for fault-management reporting. It includes an internal latch that stores the fault conditions when a signal is received, allowing the processor to analyze and report any power system errors. It also includes an integrated watchdog timer to reset the system when signal failures occur.

In summary, the LTC2960IDC-4 is a highly flexible and powerful PMIC supervisor designed for a wide range of applications. It offers excellent tolerance accuracy, hysteresis, voltage loop control, fault-management reporting, and integrated temperature sensing. With its wide range of trim options and configurable reset or interrupt logic, it is an ideal choice for power system monitoring and protection.
