PMIC – Supervisors: X4165S8T1 Application Field and Working Principle

Power management integrated circuits (PMICs) are electronic devices that control the power consumption patterns of electrical components by regulating the voltage and current used by the components. PMICs are used to ensure efficient operation of the device in applications like computer, digital TV commercial and automotive power systems. Supervisors are one type of PMIC, which are devices that provide protection for the power system and certain functions, such as voltage and current monitoring, temperature protection, and over-voltage/over-current protection. The X4165S8T1 is an example of a supervisor PMIC, and it is used in a wide range of applications, including smart phones, tablets, servers, set-top boxes, and other intelligent electronics.The X4165S8T1 is a four-phase switching regulator supervisor designed to work with point-of-load (POL) DC-DC converters. It offers comprehensive power system control, monitoring, protection, and sequencing for systems with multiple power rails. The X4165S8T1 includes three supervisor functions – over-voltage protection, under-voltage protection and over-temperature protection – and it can also be used as an input under-voltage monitoring function. It also features an operating voltage range of 2.7V to 5.5V and a standby current of 1.45μA.The X4165S8T1 works by monitoring the input and output voltages of a system and adjusting the current supplied accordingly. It also monitors the temperature of the power system, and if the temperature exceeds a pre-set threshold the X4165S8T1 will reduce the current supplied to the system, thus protecting it from damage. The X4165S8T1 also features over-voltage, under-voltage, and over-temperature protection; if the system’s voltage exceeds a certain threshold it will shut down the system to protect it from damage.In addition to its protection functions, the X4165S8T1 also provides power sequencing for systems with multiple power rails. It can be used to transition power from one rail to another in a pre-set sequence. This is particularly useful for applications such as multi-rail power supplies, where the transition from one rail to another must occur in a specific order. The X4165S8T1 also offers a wide range of monitoring features such as +12V, -12V, and +5V voltage monitoring.The X4165S8T1 is designed to offer enhanced reliability and safety when working with multiple power rails. It is suitable for applications such as consumer electronics, automotive and industrial power systems, as well as portable computing platforms. It can also be used in a wide range of voltage and current conditions. The X4165S8T1’s features and protection functions make it the ideal choice for applications that require reliable power control and monitoring, such as those found in mobile systems and other intelligent electronics.
