PMIC or Power Management Integrated Circuit (PMIC) supervisors are electrical circuits used for controlling and monitoring the power supply of various systems. The APX803S-29SA-7 is one such supervisor specifically designed for high current power management applications. In this article, we will discuss the application fields and working principle of the APX803S-29SA-7.

The APX803S-29SA-7 is a simple supervisor with two inputs – a power input and an enable input. It uses a single power input and has a single output, which is connected to the system’s power supply. The enable input allows the device to be set to either an enabled or disabled state. When the enable input is in the enabled state, the output will remain active, even when the power supply voltage falls below a certain threshold. When the enable input is in the disabled state, the output will be turned off.

The APX803S-29SA-7 is a very versatile supervisor and can be used in a wide variety of applications. It is often used in industrial and automotive systems, as well as low-power applications. It can also be used for high-current power management applications, as it is designed to manage up to 15A peak current. Some of the most common applications for the APX803S-29SA-7 include fuel pumps, oil pumps, cooling fans and other high current power requirements.

The APX803S-29SA-7 features a wide supply voltage range with a maximum of 32 V. It also has an adjustable output current limit, which allows the user to set the maximum current the output can deliver. This feature can be used to protect the system from high current surges. The APX803S-29SA-7 also has built-in over-temperature and over-current protection and can be set to recognize input glitches or disturbances.

The working principle of the APX803S-29SA-7 is relatively simple. It uses an integrated circuit (IC) to sense the power supply voltage, and when the voltage falls below a certain threshold, the device will output a signal to the system’s power input. This signal will then shut down the system’s power supply. When the power supply voltage rises back above the threshold, the supervisor will output an active signal again and the system will be powered back on.

The APX803S-29SA-7 is a powerful and versatile supervisor that can be used in a variety of applications. It is especially useful in high-current applications due to its ability to manage up to 15A of peak current, and its protection mechanisms for over-temperature and over-current conditions. Its simple operation and wide supply voltage range make it a great choice for power management applications.
