The APX803L-12SA-7 is a specialized power management integrated circuit (PMIC) used for supervisors, also commonly called voltage supervisors, for monitoring and maintaining stable power signals. This PMIC is used in a variety of industrial, consumer, telecommunications, and personal computing applications. The APX803L-12SA-7 comes in a small form factor making it ideal for designs where space is at a premium.

This PMIC has two operating voltage ranges, the first being 4.5-5.5V and the second 9-12. The 4.5-5.5V range is the optimal choice for 3.3V core logic and 5V I/O levels whereas for 5V related applications the 9-12 voltage range is preferred. It is important to note that the APX803L-12SA-7 should be used only in applications where the input voltage never exceeds its specified voltage range.

The APX803L-12SA-7 has a number of features designed to make it useful in monitoring a range of power supply configurations, with a single or dual output, both static and dynamic. It is capable of detecting any type of open drain or active high/low output, as well as voltage override and temperature override sensor input. It can detect any overvoltage or undervoltage conditions, and control a variety of output enable features, such as output voltage enable, output enable off-board detection, and manual enable/disable.

Apart from these features, the APX803L-12SA-7 is also equipped with a reset time generator which is used to control external reset pins. It is capable of providing a reset pulse when the voltage falls below a certain set threshold. The reset pulse duration can be easily set by adjusting the external R1 and R2 resistors. This is an important feature for ensuring that the system remains in a stable state even when the power supply voltage varies abruptly.

In addition to these features, the APX803L-12SA-7 is also equipped with an adjustable active low watch dog timer (WDT). This WDT is used to detect when the system is no longer receiving the correct voltage levels and reset the system in order to prevent any undesired operation. This watchdog feature can be easily adjusted to monitor overvoltage, undervoltage, or static and dynamic signals.

Overall, with its wide operating voltage range, and support for multiple power configurations, the APX803L-12SA-7 is a great choice for producing reliable power management solutions. Its versatile design, features and ease of use make it a great option for any application requiring voltage monitoring and stable power supplies.
