The MCP73834-CNI/MF is a division of the PMIC line. A PMIC, or Power Management Integrated Circuit is something used to convert, manage and optimize electrical power in a system. The MCP73834-CNI/MF specifically falls under the component line of PMIC battery chargers. It is a high-performance, low-cost, and easy to use Linear Li-Ion/LiFePO4 battery charger. It features regulated current, temperature, and time parameters to protect the battery during charging, thereby increasing battery life and improving system performance.

The MCP73834-CNI/MF is a highly efficient battery charger used to charge single-cell Li-Ion or LiFePO4 batteries. It operates from an input supply between 3.8V and 6V, with low quiescent current ideal for battery applications. Its features make it a great choice for many applications such as portable electronics, mobile phones, laptops, and other battery powered applications.

The MCP73834-CNI/MF has plenty of unique features that make it an ideal choice for battery applications. It is available in two versions: fast-charge and constant-charge. The fast-charge version charges batteries in as little as two hours, while the constant-charge version charges batteries over 6 to 12 hours. It also offers several safety features including overvoltage, overtemperature, and short-circuit protection. In addition, it has a built-in power selector pin to select between 500mA, 1000mA, 1500mA, and 2000mA charge currents.

The MCP73834-CNI/MF works through a regulated current source to charge the battery at a constant current rate, up to the preset voltage limit. It has a negative temperature coefficient protection circuit which monitors the temperature of the Li-Ion/LiFePO4 battery and reduces the charge current when the battery temperature is too high. The current limit is restarted when the battery has cooled down to a safe temperature. It also has a separate safety timer which will shut down the charger if the battery is not charged within a programmed time limit.

The MCP73834-CNI/MF is a great choice for many different battery applications due to its many features and its low cost. The device is designed to be low power, easy to use, and safe. It is well suited for a wide range of applications, from portable electronics to mobile phones, to laptop computers and many other battery-related applications. It is a great choice for anyone looking for a reliable, low cost solution for their battery needs.
