Power Management Integrated Circuits (PMICs), also known as power ICs or power integrated circuits, are embedded semiconductor devices that provide a wide range of functionalities such as voltage regulation, power switching, and charging. PMICs are designed to handle various system-level power requirements, ensuring optimum performance and efficiency. Battery chargers, in particular, refer to the branch of PMICs that can detect and charge batteries. Among the many types of battery chargers available in the market, MCP73833T-GI/UN is especially noteworthy. This article will discuss the applications and working principle of MCP73833T-GI/UN.

MCP73833T-GI/UN is a Li-Ion (Lithium-Ion) battery charger that provides professional grade control for Li-Ion battery charging operations. It uses microcontroller interface communication protocol, Pulse-Skipping charge mode with current and thermal regulation, end-of-charge detection, safety timer and other features, making it ideal for use in cell phones and other portable and embedded applications. It is particularly suitable for use in battery-powered clocks, vehicle-mounted systems, medical analyzers, remote control equipment and other battery powered systems.

MCP73833T-GI/UN is an example of a step-up type of battery charger, which means that it charges a battery by increasing the voltage at the battery terminals. To do this, it uses onboard power transistors to step up the input voltage, which is usually between 2-3V. This higher voltage facilitates the charging process and the resulting current supplies power to the battery. The voltage is regulated to the preset level and the battery is charged to its full capacity, resulting in optimum performance and efficiency.

The working principle of MCP73833T-GI/UN can be divided into two main parts. The first part is the input power section, which converts the DC voltage from the battery into a higher voltage suitable for charging the battery. It is accomplished using a power transistor, which is controlled by the voltage sensing circuit. This sensing circuit is used to detect the level of the input voltage so that the power transistor can adjust its output voltage accordingly, ensuring optimum charging. The second part is the charge control section, which is responsible for switching the battery charging on or off and setting the appropriate charging rate. This is done via the charge control logic, which is based on the voltage and current of the battery, the temperature of the battery, and other environmental conditions.

MCP73833T-GI/UN is a versatile and feature-packed battery charger that is suitable for use in a wide range of applications. It has been designed to significantly reduce development time, cost and board space. Its efficient power conversion and intelligent charge control logic make it an ideal choice for portable device and embedded applications. Its small size, high efficiency, low external component counts, and other features make it a highly popular choice for battery-powered systems.
