The MCP73833-AMI/MF is a highly specialized battery charging circuit specifically designed by Microchip to provide precise voltage and current regulation to Lithium-Ion/Lithium-Polymer batteries with little or no external programming. It can also be used to provide accurate currents and voltages to other types of rechargeable batteries such as NiMH/NiCd, Lead Acid, and more. As the name implies, this battery charger circuit is highly efficient and operates at extremely low quiescent current levels, making it an ideal choice for power-sensitive applications.

The MCP73833-AMI/MF is capable of charging a single cell Lithium-Ion/Lithium-Polymer battery from an input power source, as well as providing precise voltage regulation for multiple cell Lithium-Ion/Lithium-Polymer batteries. It has a very wide input voltage range, from 2.8V to 18V, and offers a wide output voltage range from 4.2V to 8.4V. It also provides two high-current feedback pins for precise current regulation, as well as two ultra-low current pins for low current operations. The MCP73833-AMI/MF is equipped with an internal temperature sensor that constantly monitors the battery temperature and maintains it at an optimal level during the charging process.

The MCP73833-AMI/MF also has several features which help to maximize the lifetime of the battery. These features include undervoltage lockout, overvoltage protection, reverse current protection, reverse battery protection, and other safety features. Additionally, it has programmable charging parameters, such as charge current limit, charge voltage limit, and charge time limit, which enables the circuit to adjust charging parameters to best suit the battery being charged.

The working principle of the MCP73833-AMI/MF is based on a voltage- and current-regulated topology. The charging circuit is designed to maintain the battery voltage at a regulated level, while simultaneously controlling the charging current in order to prevent overcharging and over-discharging of the battery. When the input voltage is greater than the minimum voltage necessary to begin charging, an internal voltage-regulator circuit is activated to precision-regulate the charging voltage. The current is controlled by an internal current-sensing circuit, which monitors the current being provided to the battery and prevents it from exceeding the set limit.

The MCP73833-AMI/MF is ideal for powering many types of portable consumer electronics, such as digital cameras, cell phones, MP3 players, and other devices that require a reliable, low-cost charging solution. Its small size and high accuracy also make it a great choice for applications in robotics and industrial automation, as well as medical devices.
