PMIC (power management integrated circuits) supervisors are essential elements in modern electronic equipment and industrial systems. They play an important role in providing power supplies with reliable control, monitoring, and protection. The DS1708RESA/T&R is one of the most commonly used power management integrated circuits (PMIC) supervisors. This article outlines the application field and working principle of the DS1708RESA/T&R.

Application Field

The DS1708RESA/T&R is a next-generation PMIC supervisor that provides many advantages compared to traditional supervisors. It was designed to handle increasing power demands in systems where both AC and DC power supplies coexist. It is suitable for embedded applications, industrial systems, and many other applications where reliable power control and monitoring are critical components. The modules come in various power capacities, from 8–20 watts.

The DS1708RESA/T&R is a “system supervisor”, which means it can control and monitor multiple power supplies from one module. This feature makes it perfect for applications that require multiple power supplies. Additionally, it features a configurable over-current protection (OCP) for each power source, as well as over-power protection (OPP), continuously-variable voltage selection (CVVS), positive temperature coefficient (PTC), and other advanced protection functions.

Working Principle

The DS1708RESA/T&R module is configured as a system supervisor, thus allowing it to control and monitor multiple power supplies from one module. This offers many advantages, such as the ability to control several different voltage levels, enable over-current protection (OCP) on each power supply, configurable voltage selection (CVVS), and enable over-power protection (OPP).

The OCP is responsible for regulating the current flowing through the power source and protecting the source from being over-driven by too much current. The CVVS and OPP features of the DS1708RESA/T&R enable the module to detect erroneous voltage levels and over-power conditions, respectively.

The PTC function of the DS1708RESA/T is enabled to protect the power supply from over-temperatures by limiting the amount of current that can be drawn from it. This feature is critical in applications where high temperatures and/or high current demand are present.

With its multiple configurations, the DS1708RESA/T&R provides powerful control and monitoring of power sources. Furthermore, the module is designed to be easily incorporated into existing systems and requires minimal programming from the user.

In conclusion, the DS1708RESA/T&R is a high-performance, next-generation PMIC supervisor that provides reliable power control, monitoring, and protection for embedded systems and other applications where multiple power supplies are essential. It features advanced protection functions, including configurable over-current protection (OCP), over-power protection (OPP), and positive temperature coefficient (PTC). As a “system supervisor”, it is capable of controlling and monitoring multiple power sources from one module, thus making it an ideal choice for applications requiring multiple power supplies.
