PMIC, or power management integrated circuit, is a general term used to describe integrated circuits which manage the power supply of a device. It includes various types of integrated circuits, such as voltage regulators, power converters, LED drivers, and supervision ICs. Supervision ICs, also known as voltage supervisors, are special ICs that can be used to monitor and regulate the voltage of a device. APX803L-28SA-7 is a low current, low voltage supervisor IC, used to provide a precision regulated reference voltage. It is mainly used in various kinds of electronic devices, ranging from cell phones and laptops to desktop computers and industrial equipment. This article will discuss the application field and working principle of the APX803L-28SA-7.

The APX803L-28SA-7 is designed for applications that require a low power, low voltage reference voltage in order to accurately regulate the output voltage of power supplies. It is mainly used in mobile devices, such as mobile phones, tablets and laptops, where a low power consumption is essential. It is also widely used in desktop computers, UPS systems, as well as in automotive, industrial and communication applications. The APX803L-28SA-7 features a three-state power supply, which allows it to switch between two different power supply voltages, depending on the application needs. The APX803L-28SA-7 also has a wide operating voltage range which makes it suitable for a variety of applications.

The APX803L-28SA-7 is a two-pin supervisor IC, with an internal voltage divider. The two pins are labeled VDD and GND. The VDD pin is used to input the voltage supply, and the GND pin is used as the ground reference. The internal voltage divider is used to compare the input voltage to an internal reference voltage to determine whether the input voltage is above or below a predetermined threshold. If the input voltage exceeds the threshold, the APX803L-28SA-7 will output a logic low signal, otherwise it will output a logic high signal. This logic low or logic high signal can be used to activate a power source or turn off certain circuit elements in order to protect the system.

The APX803L-28SA-7 features an adjustable threshold voltage, which can be adjusted using its internal voltage divider. This allows the threshold voltage to be adjusted to match the application needs. Additionally, the threshold voltage can be set to a level which is lower than the supply voltage for extra protection. Furthermore, the APX803L-28SA-7 also has an internal delay circuit, which prevents it from triggering an output signal too quickly. This prevents false triggering and ensures reliable operation.

The APX803L-28SA-7 is an excellent voltage supervisor IC, which can be used in a variety of applications. Its adjustable threshold voltage, wide operating voltage range, and internal delay circuit make it ideal for low power applications, such as mobile devices. It is also used in industrial and automotive applications, where reliable protection of the system is essential. Therefore, the APX803L-28SA-7 is a valuable component in today’s power management systems.
