Power management is essential when it comes to managing and controlling the power consumption of a circuit, system, or device. In this article, we will take a closer look at a specific PMIC (Power Management IC) product, the MAX17562AUD+, and examine its application field and working principle.

Overview

The MAX17562AUD+ is an integrated step-down and step-up PMIC designed to automatically regulate the power within a standard Li-Ion and Li-Ion battery pack. It combines advanced power management functions such as battery cell balancing and advanced diagnostics, while also providing a flexible power path and control. It is designed to efficiently control and manage a single Li-Ion battery cell or a Li-Ion battery pack that consists of 4 or 8 cells. It allows designers to quickly and easily develop power delivery architectures that are safe and reliable.

Application Field

The MAX17562AUD+ is typically used in space-constrained portable and handheld devices. Examples of such applications include, but are not limited to, laptops, tablets, power tools, cameras, wearables, and other IoT (Internet of Things) devices. It is also widely used in transportation such as cars and motorcycles.

In addition, the MAX17562AUD+ is well suited for communications and data processing, industrial, military and aerospace, power supply, medical, and point-of-load applications. Due to its highly integrated, space-saving package, the MAX17562AUD+ can be used in a variety of space-constrained designs such as slim notebooks and mobile handhelds.

Working Principle

At the core of the MAX17562AUD+ is the integrated current monitoring system. This system is responsible for regulating the power delivered to the device. It uses an integrated low-noise 0.5μA current monitor to measure the voltage within the battery pack. This voltage is then converted to a current, which is then used to accurately regulate the output power. The MAX17562AUD+ also utilizes an integrated charge pump and linear regulator to maintain a constant voltage on the cells.

The MAX17562AUD+ also features a unique circuitry for fast and accurate balancing of the individual cells. This ensures that all cells in the battery pack remain balanced during a charge or discharge cycle. This ensures battery charging and discharging is safe, efficient and optimized.

The MAX17562AUD+ also features a wide range of advanced diagnostics capabilities. It can detect faults such as overdischarge, overcharge, open circuit and short circuit in a single cell or multiple cells of a Li-Ion battery pack. It can also detect cells that are not used or charged correctly and advise of corrective action.

Conclusion

The MAX17562AUD+ is an integrated step-down and step-up PMIC designed to automatically regulate the power within a standard Li-Ion and Li-Ion battery pack. It features advanced power management functions such as battery cell balancing and advanced diagnostics, while also providing a flexible power path and control. It is typically used in space-constrained portable and handheld devices and is well suited for a variety of communications and data processing, industrial, military and aerospace, power supply, medical, and point-of-load applications.
