Power management integrated circuits (PMICs) are essential components used to provide power delivery and system management in many electronic devices. PMICs can reduce the number of components in a design, minimize board space, and improve system reliability and reduce costs. Supervisors are specific types of PMICs, designed to detect and react to system conditions such as over and under voltage, over and under temperature, and brown out conditions.

APX803L20-17SA-7 is a PMIC supervisor from Apex Microtechnology. It is designed to monitor and perform system control functions for a wide range of applications. It is capable of operating over extended temperature ranges, supports low power state, and offers accurate and reliable threshold detection to protect the application from damage due to over or under voltage or temperature conditions.

The APX803L20-17SA-7 offers a wide operating voltage range from 2.3V to 17V, operation temperature range from -40°C to +125°C, a fast response time of 20us, and a low shutdown current of 50nA. It has a wide range of features that make it ideal for a variety of applications. These features include programmable delay time, programmable reset timer, user configurable assertions on reset, reset source selection, reset status flag, programmable reset polarity, voltage monitor delay, and open/short detect override.

The APX803L20-17SA-7 is widely used in consumer electronics, automotive, and industrial applications. It finds applications in power supplies, voltage regulators, computers, cell phones, and handheld devices. In automotive applications, it is used for power supply and system control, such as engine control, airbag control, brake control, etc. It is also used for gas and fluid sensing, medical diagnostics and equipment, and agricultural applications.

The APX803L20-17SA-7 works by detecting the input voltage of a system and then comparing it to a voltage threshold that can be programmed by the user. If the voltage drops below the threshold, the reset circuit is activated, which triggers system reset or some other user-defined action. This ensures that the system remains within the allowed voltage limits and prevents damage to the application due to voltage surges.

The APX803L20-17SA-7 is a cost-effective and reliable way to ensure that electronic system remain safe and operational, even in the harshest conditions. With its wide range of features and application breadth, the APX803L20-17SA-7 is a popular choice for many applications requiring voltage supervision.
