Introduction to PMIC - Supervisors

Power Management Integrated Circuit (PMIC) is a type of integrated circuit known for its energy efficient power management solution abilities. The PMIC is designed to help power devices with the most efficient way possible by regulating and controlling the power being used within the devices. PMICs come in various shapes, sizes and forms.PMICs can be broken down into three main categories, which include PMUs,REGs and Supervisors. PMUs are more complex power management ICs that are used to monitor and manage the current state of a device and its related components. REGs, often referred to as Volt-Regs, act as voltage regulators, allowing for unprecedented control over the output voltage and regulation of power usage.Finally, Supervisors are specialized integrated circuits that are used to supervise and protect the system from any unexpected occurrences in terms of power supply or temperature. Supervisors are typically equipped with features such as Watchdogs, temperature and power shutoff or supervisor systems, or even reset control signals.
