PMIC (Power Management Integrated Circuit) is a type of microelectronic integrated circuit that manages power flow in different electronic systems. They are typically used in applications which require managing large amounts of electrical power over extended periods of time, such as in laptops and other mobile devices. A Supervisors is a special type of PMIC, specifically designed to be used as an active power management solution. They are usually used in applications such as voltage monitoring and generating resets.

The APX811-23UG-7 device is a power management integrated circuit (PMIC) specifically designed to be used as a supervisor. It is a four-channel power supervisor designed specifically to provide precise voltage monitoring, reset generation, and system power management functions. The APX811-23UG-7 has four independent voltage monitor/reset channels and one power-on reset (POR) signal. It has four thresholds, channels 1 to 4 which can be individually programmed for over voltage (OV), under voltage (UV) and power-on reset (POR) functions.

In its normal operating mode, the APX811-23UG-7 monitors the junction temperature of the IC, the supply voltage and the channel voltages. If any of the monitored parameters falls below a predefined level, the IC will generate an active reset signal. The active reset signal is routed to system components that require a reset for proper operation. In addition, the active reset signal can be used to automatically shut down the system in case of an OV/UV or POR fault.

The APX811-23UG-7 is frequently used in applications such as: Server and Data Center Management Systems, Industrial Power Control, Automotive Power Management, Multiprocessor Systems, Mobile and Wireless Communication, Networking Systems and High-end Motor Control.

The working principle of the APX811-23UG-7 can be summarized as: The IC monitors the junction temperature, the supply voltage, and four independent voltage monitor/reset channels. It also contains a power-on reset (POR) signal. It uses these signals to generate an active reset signal in case of an over-voltage (OV) or an under-voltage (UV) fault, or a power-on reset (POR) event. This reset signal is routed to the system components that require a reset for proper operation. The APX811-23UG-7 can also be used to automatically shut down the system in case of an OV/UV or POR fault.

The APX811-23UG-7 is a versatile and reliable power management integrated circuit (PMIC) specifically designed to be used as a supervisor, making it ideal for use in high-end applications such as server and data center management systems, industrial power controls, multiprocessor systems, mobile and wireless communications, and networking systems. Its ability to monitor junction temperature and supply voltages, and generate an active reset signal on demand make it a powerful and invaluable tool in any power management application.
