Microchip Technology, Inc. PMIC - Battery Chargers MCP73213T-A6SI/MF

The MCP73213T-A6SI/MF is a dual-cell Li-Ion/Li-Polymer battery charge management controller designed for compact and cost-sensitive applications. It features integrated input overvoltage protection, a pass transistor, current sensing, and reverse discharge protection, making it suitable for portable devices. The device operates using a constant current/constant voltage charging algorithm with thermal regulation, ensuring optimal charging performance while maintaining reliability. The MCP73213T-A6SI/MF supports battery charge voltage options of 8.20V, 8.40V, 8.7V, or 8.8V, and allows for programmable fast charge currents ranging from 130 mA to 1100 mA. It includes preconditioning options for deeply depleted cells, an integrated precondition timer, and automatic end-of-charge control with selectable minimum current ratios. The device operates over a wide temperature range of -40¬8C to +85¬8C and is packaged in a compact DFN-10 (3 mm x 3 mm) format. This controller is suitable for applications such as digital camcorders, portable media players, ultra-mobile personal computers, netbook computers, handheld devices, and low-cost 2-cell Li-Ion/Li-Poly chargers. Its robust design and flexibility make it a viable option for engineers looking to implement efficient battery charging solutions in their projects.
