The MCP73834T-FCI/MF from Microchip Technology is a highly advanced linear charge management controller designed for space-limited and cost-sensitive applications. It is suitable for charging single-cell Lithium-Ion and Lithium-Polymer batteries.
This IC features a constant current/constant voltage charge algorithm with thermal regulation. It offers a programmable charge current up to 1.1A and supports preset voltage regulation options including 4.2V, 4.35V, 4.4V, or 4.5V with high accuracy. The device includes integrated pass transistor, current sense, and reverse discharge protection.
Key features include selectable preconditioning and charge termination options, automatic recharge control, two charge status outputs, and a cell temperature monitor. It also supports low-dropout linear regulator mode and automatic power-down when input power is removed. The MCP73834T-FCI/MF is available in a 10-DFN (3x3 mm) package and is designed for surface mounting.
Applications for this component include portable devices such as personal data assistants, cellular telephones, digital cameras, MP3 players, Bluetooth headsets, and USB chargers. It adheres to USB power bus specifications when charging from a USB port.
