PMIC (power management IC) devices have become increasingly important in the development of battery charger products, as modern electronics devices have continued to become more complex and power-hungry.The MCP73833T-AMI/UN is a highly accurate PMIC device specifically designed for multi-chemistry battery charger applications. It is a cost-effective approach that combines ease of use with efficient power management, making it ideal for applications demanding minimal system design effort. This device features an integrated buck-boost regulator with battery voltage and temperature sensing, while also compliant with the USB power delivery (PD) protocol. This PMIC device promises to provide designers a high degree of control over the charging of their portable devices.

A battery charger is a device used to replenish the energy stored in a rechargeable battery by supplying electrical energy. A PMIC battery charger then is an integrated circuit that performs functions suggested by its name: it manages the power of a battery charging process. The MCP73833T-AMI/UN PMIC Battery Charger effectively couples a power source such as USB, Solar, wall adapters to the charge terminals of a rechargeable battery, maintaining a constant voltage percent voltage. The device itself is an automotive-grade buck-boost regulator in a 2.9mmx2.9mm QFN-40 package. It is built with a highly efficient buck-boost DC/DC converter capable of carrying output currents as high as 1.5A.

The MCP73833T-AMI/UN is specifically designed for single-cell Lithium-Ion batteries. It offers a variable charge current and adjustable voltage with 3 preset modes: Constant Voltage, Constant Current, and Constant Current-Constant Voltage (CC-CV). This versatile device offers three features to ensure that the system is safe and reliable. These features are, charge current limit, thermal regulation, and IEEE802.3af compliant detection for power source selection. The CC and CV set points are factory programmed, allowing designers to reduce their time to market.

The USB power delivery protocol built into the MCP73833T-AMI/UN allows for easier integration into quality battery charger systems. Furthermore, the integrated power capabilities allow the designer to use a single device instead of multiple discrete components, saving considerable time in the design and development cycle. This device also offers a power saving feature that reduces further power consumption and increases the battery life of a connected device.

To ensure maximum safety and reliability, the MCP73833T-AMI/UN PMIC Battery Charger utilizes many features to prevent possible damages due to incorrect usage. These mechanisms include high voltage (18V) and high current (2A) protection, while also featuring internal double-protection FETs and voltage limit fold-back. Furthermore, the device provides over-charge, over-temperature and timer protection so that effective battery charging can be accomplished in a safe environment.

The MCP73833T-AMI/UN PMIC Battery Charger provides an excellent solution for single-cell Lithium-Ion battery chargers, for use in modern electronics applications. It is a diverse, programmed charger which efficiently manages the charging process, making it suitable for use in a range of applications from consumer electronics and wearable devices to automotive and industrial equipment.
