Microchip Technology's MCP73832T-2ACI/0T Charge Management Controller

The MCP73832T-2ACI/0T is a highly integrated linear charge management controller from Microchip Technology, designed for use in space-limited and cost-sensitive applications. This miniature single-cell, fully-integrated lithium-ion/lithium-polymer charge management controller is available in a tiny 5-TDFN thermally efficient package, making it an ideal solution for portable electronics.

This advanced charge management controller offers a simple and reliable solution for charging batteries. It incorporates a constant-current/constant-voltage charge algorithm with selectable preconditioning and charge termination. The charge voltage is fixed at 4.2V, and the charge current can be set externally with a single resistor. This flexibility allows designers to tailor the charge parameters to suit various battery sizes and chemistries.

The MCP73832T-2ACI/0T features a range of safety and protection features, including automatic recharge, thermal regulation, and safety timers. Over-temperature protection ensures that the charge process is safely managed even under abnormal conditions. The device also includes under-voltage lockout (UVLO), ensuring the battery is not charged unless there is a sufficient supply voltage.

With its small footprint and integrated features, the MCP73832T-2ACI/0T is particularly suited for portable applications such as personal media players, Bluetooth headsets, handheld devices, and other USB-powered gadgets. Its ease of use and implementation make it a favorite among designers looking to streamline the development process while maintaining high performance and reliability in their charging circuits.

Overall, the MCP73832T-2ACI/0T from Microchip Technology is a compact, efficient, and versatile charge management solution that meets the demands of modern portable electronics for safe and fast battery charging.
