Integrated circuits are an important part of any electronic device and system. There are a variety of ICs available in the market including PMIC supervisors, which can provide power management, monitoring, and control functions within electronic products. The APX803L05-31SA-7 is a low-cost low-power voltage supervisor based on PMIC technology and it is widely used in a variety of applications. The following article will discuss the application field and working principle of this IC.

APX803L05-31SA-7 Application Fields :

The APX803L05-31SA-7 is a supervisor IC that can be used to monitor voltage levels and ensure the safe operation of electronic products. It is often used in mobile phones, medical and industrial devices, automotive, aerospace and other areas. It can provide voltage supervision for a variety of different applications, ranging from basic 1.8V single voltage monitoring to more complex multiple voltage monitoring circuits. The APX803L05-31SA-7 can also provide a reset output when the supplied voltage drops below a certain threshold, which allows the system to be reset and return to a safe state.

APX803L05-31SA-7 Working Principle:

The APX803L05-31SA-7 is a voltage supervisor IC that utilizes an on-chip linear voltage regulator to monitor voltages. It has an internal bandgap reference voltage source and a comparator to detect when the supplied voltage drops below a certain level. When this occurs, the APX803L05-31SA-7 will pull the reset output low and initiate a reset of the system. The reset output will remain low until the supplied voltage rises above the reset threshold, at which point the reset output will go high and the system will be allowed to resume operation.

The APX803L05-31SA-7 is also capable of detecting a brown-out condition, which occurs when the voltage supplied to the IC is lower than the expected voltage level. In this case, the IC will still pull the reset output low, thus causing a system reset to occur and preventing the system from continuing to function unless the supply voltage is increased to an acceptable level. This feature is especially useful in automotive, industrial and medical applications, where sudden voltage drops can cause system failure which could potentially be hazardous.

The APX803L05-31SA-7 has a wide operating temperature range of -40 to +85 degrees Celsius, which makes it suitable for use in a variety of temperature environments. It also has a low quiescent current of only 2.4uA, making it very power efficient and suitable for use in battery-operated or low-power devices. The APX803L05-31SA-7 is also available in a variety of package styles, including DIP, DMP, and SOIC, allowing it to be used in both through-hole and surface mount applications.

Conclusion:

The APX803L05-31SA-7 is a low-cost, low-power voltage supervisor IC that can be used to monitor and control voltages in a variety of electronic applications. It is easy to use, provides accurate and reliable voltage supervision, and has a wide temperature range, making it suitable for many different applications. In addition, it has a low quiescent current, making it power efficient and suitable for use in battery-powered devices. With its wide range of features and capabilities, the APX803L05-31SA-7 is an ideal IC for many types of electronic projects and products.
