PMIC (Power Management Integrated Circuit) supervisors play an important role in the power management system. They can ensure the reliability of the system and maintain the system’s stability by detecting a wide range of voltage and temperature conditions. The APX803S-44SR-7 is a supervisor IC with integrated POR (Power-on Reset) and brown-out reset protection, which can be used in many applications. In this article, we will discuss the application fields and working principles of the APX803S-44SR-7 supervisor.

The APX803S-44SR-7 is a versatile power management supervisor chip that can be used in a wide range of applications. It is typically used in industrial and automotive systems, such as solar power systems, sensing and control systems, telecom systems, automotive infotainment systems, etc. This supervisor IC is also often used in energy storage systems, as it helps regulate the power flow from batteries and other sources. The APX803S-44SR-7 can also be used in medical and healthcare-related applications, such as monitoring and managing medical devices.

The APX803S-44SR-7 supervisor IC can detect a wide range of voltage and temperature conditions, making it suitable for use in a variety of applications. The IC can monitor two independent voltages and provide two independent error signals for the two separate voltages. The APX803S-44SR-7 employs an integrated power-on reset (POR) and brown-out reset (BOR) circuit, which provides a reliable protection of the system by resetting the system when voltage or temperature levels exceed certain values. The supervisor IC also features an adjustable voltage thresholds that can be adjusted to meet the needs of the system.

In addition, the APX803S-44SR-7 supervisor IC includes an adaptive Brown-Out-Detection (BOD) circuit which is used to monitor the supply under voltage and can detect voltage drops when the system is in the low-power mode. The BOD circuit also features a selectable reset signal output that can be used to apply a reset to the system and signal a shutdown when the voltage drops below the BOD threshold. The BOD circuit can also be configured to signal a ADC range error or other error conditions.

The APX803S-44SR-7 supervisor IC also features a number of system control functions including logic powers for external control logic, active low-power control, selectable pull-up control and adjustable delay times. Additionally, the APX803S-44SR-7 supervisor IC has an integrated watchdog timer, which can be used to ensure the stability of the system by automatically resetting the system if certain conditions are not met.

The APX803S-44SR-7 supervisor IC is a versatile, low-power supervisor which can be used in a variety of applications. The IC’s integrated Power-on Reset (POR) and Brown-out Reset (BOR) features are ideal for providing reliable protection of the system. The adaptive BOD circuit is useful for monitoring the supply under voltage and resetting the system in low-power mode. The APX803S-44SR-7 also includes system control functions and an integrated watchdog timer, making it an excellent choice for a wide range of applications.
