Microchip Technology MCP73833T-BZI/MF
The MCP73833T-BZI/MF from Microchip Technology is a highly integrated, linear charge management controller designed for single-cell Li-Ion or Li-Polymer batteries. This advanced battery charging solution is ideal for portable applications where space is at a premium and performance is not to be compromised.
This charge management controller integrates several key features that contribute to its effectiveness and ease of use. It boasts an onboard pass transistor, current sense, reverse discharge protection, and a precision reference to ensure accurate charge voltage control. The MCP73833T-BZI/MF operates in a constant current/constant voltage charge algorithm with selectable preconditioning and charge termination.
The device offers a programmable charge current from 15 mA to 500 mA via an external resistor, allowing designers to tailor the charge rate to the specific needs of their application. Additionally, the MCP73833T-BZI/MF provides an array of safety features including thermal regulation, which maximizes the charge rate without the risk of overheating, and a charge safety timer for additional protection.
Communication with the host microcontroller is straightforward, thanks to the status outputs that indicate charge cycle completion and fault conditions. These outputs can be used to trigger LED indicators or interface with the host system to signal the battery status.
The compact package of the MCP73833T-BZI/MF, available in a 10-MSOP footprint, ensures a minimal impact on the overall design size, making it an excellent choice for portable devices such as personal media players, digital cameras, Bluetooth headsets, and other USB chargeable devices.
