Introduction

The AP1701EWL-7 is a type of PMIC - Supervisors, the original purpose of which was to provide protection to run-of-the-mill GPUs, CPUs, and DSPs from power surges, spikes and other voltage irregularities. However, due to its ability to perform multiple tasks in a staggeringly-small package, the application fields of PMIC - Supervisors have grown exponentially over the years. This article will discuss the application field and working principle of the AP1701EWL-7.

Application Field

The AP1701EWL-7 was purposely designed to provide over-voltage protection, while providing features such as UVLO(Under Voltage Lock Out), adjustable OVLO(Over Voltage Lock Out) thresholds, adjustable VCC power-up/ power-down delays, and adjustable soft-start up-length. These features have made this particular PMIC - Supervisors ideal for powering SoCs, FPGAs, and ASICs. Furthermore, with its advanced level-shifter technology this PMIC is capable of handling multi-voltage buses, allowing it to be used for automatic voltage conversion for various digital circuit systems. One interesting application of the AP1701EWL-7 is in the field of robotics, as it can be used to regulate the power supplies of servo motors.

Working Principle

The working principle of the AP1701EWL-7 can be broken down into 3 parts: voltage monitoring, voltage protection and level shifting. Firstly, the device features a highly accurate voltage monitoring circuit, with a +/- 2.0% monitoring accuracy, that is capable of monitoring voltages up to 25V. This is especially useful when it is used to monitor the movements of a robotic arm, or to detect voltage value changes in voltage regulator modules (VRMs). Secondly, the AP1701EWL-7 comes with a built-in over-voltage protection mode, which is triggered to prevent over-voltage conditions from damaging the system. By detecting voltage fluctuations and regulating them, the device is also capable of providing soft-start capabilities, allowing for smooth and power supply operation.

Finally, the AP1701EWL-7 also features an advanced level shifter technology, allowing for automatic voltage conversion between digital circuits. This is useful for you to be able to convert different power signals between multiple levels. This is especially useful when it comes to sending data between devices that run on different voltage supplies. For example, the device is capable of converting between a 12V-supply circuit and a 5V-supply circuit without the need for any external components.

Conclusion

In conclusion, the AP1701EWL-7 is an incredibly versatile and powerful PMIC - Supervisors that offers an array of features and capabilities that can be used in a myriad of applications. Its superb voltage monitoring, over-voltage protection, level-shifter technology, and soft-start capability are what makes it such a great choice for powering SoCs, FPGAs, and ASICs. Its uses are far-reaching and its applications are vast, ranging from robotic systems to video game consoles. With its highly accurate monitoring, robust protection, and advanced level shifter technology, the AP1701EWL-7 is certainly one of the most powerful PMICs - Supervisors available on the market today.
