The MCP73871-2AAI/ML is a PMIC specifically designed for battery-powered applications which features lithium-ion and lithium-polymer charge-management as well as battery monitoring, making it a powerful piece of IC. As its name implies, this IC features two main features: a charge management system and a battery monitoring system. Let\'s take a closer look at both of these features and understand how this IC can be useful in applications.

The Charge Management System (CMS) is the key feature of the MCP73871-2AAI/ML and is responsbile for safely and efficiently charging a battery of any chemistry. To do this, the IC utilizes a three-step charging algorithm governed by two parameters: charge current and charge voltage. During the first step of charging, the IC monitors the voltage on the battery and, if it exceeds a predetermined level set by the user, it transitions to the second step and begins to decrease the charge current. This process continues until the battery is fully charged, at which point the IC returns to step one and the cycle repeats.

The second major feature of the MCP73871-2AAI/ML IC is its Battery Monitoring System (BMS). This monitoring system allows the user to easily monitor the charge level of their battery using one of the IC\'s built-in input pins. The BMS utilizes an analog-to-digital converter to accurately gauge the charge level of the battery and can be used to determine when the battery needs to be recharged.

The MCP73871-2AAI/ML is an incredibly versatile PMIC and due to its ability to handle multiple battery chemistries, it is ideal for many portable applications. Examples of applications where this IC could be utilized would include powered bicycles, portable medical devices, and even some consumer electronic devices such as smartwatches and fitness/activity trackers. Each of these applications requires a powerful and efficient charging system that can manage multiple types of batteries and the MCP73871-2AAI/ML is just the IC to do it.

In summary, the MCP73871-2AAI/ML is a powerful PMIC specifically designed to manage external battery-powered applications. It is capable of managing multiple battery chemistries, and utilizes a three-step charging algorithm. Additionally, it also features a built-in battery monitoring system, which allows users to easily monitor their battery charge levels. These features make this IC a powerful tool in many types of applications, from portable devices to consumer electronics.
