PMIC (Power Management Integrated Circuit) is an integrated circuit that combines several power converters, circuit protection devices and other power management functions into a single unit. Battery chargers are a type of PMIC that play a crucial role in providing reliable power and efficient charging of modern portable electronic devices. The MAX17006ETP+is a high-performance linear charger with a configurable, synchronous switching buck-boost converter that can adjust the applied voltage. This article will discuss the application fields of the MAX17006ETP+ and its working principle.

Application Fields

The MAX17006ETP+ is designed for space-constrained battery-powered systems, such as those used in wearables, home health, and portable medical applications. Furthermore, its two operating modes, either the Boost Mode for trickle charging, or the Buck-Boost Mode for fast charging, make it ideal for applications such as smartphone, tablet and laptop charging. Moreover, the device features excellent load regulation, no audible noise in boost mode, and is a precision current-limit charger. Additionally, it has a wide 3.3V to 5.5V input voltage range and can be optimized for either low or high input voltage charge profiles. Furthermore, it can be used in automotive or industrial applications, or in any other power system that requires efficient, long-term reliable power.

Working Principle

The MAX17006ETP+ integrates a buck-boost controller and a linear charger in one IC. The buck-boost converter synchronizes its inputs and outputs so as to accurately control the output voltage, regardless of the input voltage. It ensures that the output voltage is always within the permissible battery charge range. When the input voltage is less than the output voltage, the chip enters boost mode, wherein it supplies power to the load. When the input voltage is greater than the output voltage, the chip switches to buck-boost mode and regulates the voltage to match that of the battery. The chip uses an armature control method to accurately control the output voltage. It maintains a constant output voltage despite fluctuations in the input voltage. Notably, the device is programmable and configurable, enabling users to customize the power output.

The MAX17006ETP+ also integrates a linear charger that uses constant current/constant voltage (CC/CV) control. It senses the battery voltage and regulates its output current to provide battery charging while preventing overcharging. It can be configured to charge quickly or slowly based on the set parameters. When the battery voltage reaches the set point, the current reduction ensures that the battery is not overcharged, and the device enters trickle charging once the battery is full. This provides a long-term reliable power supply with improved end-of-charge accuracy.

The MAX17006ETP+ also features an internal power FET, an output voltage monitor, a low voltage lockout (LVO), an overvoltage protection (OVP) and an output current monitor. These features allow for better system protection and increased safety. Furthermore, the device is designed with power path management, which allows the device to automatically detect when the main power source is removed and the battery is supplying the power. This feature makes the device ideal for use in battery-powered systems.

In conclusion, the MAX17006ETP+ is a high-performance, configurable, synchronous switching buck-boost charger, ideal for use in applications such as wearables, home health and portable medical devices, as well as automotive and industrial applications. Its precision current-limit charging, excellent load regulation and wide input voltage range make it an ideal solution for providing reliable power and efficient charging of modern portable electronic devices.
