Microchip Technology, Inc. PMIC - Battery Chargers MCP73830T-2AAI/MYY

The MCP73830T-2AAI/MYY is a highly integrated Li-Ion battery charge management controller designed for space-constrained applications. It supports single-cell Li-Ion and Li-Polymer batteries, utilizing a constant-current/constant-voltage charge algorithm to optimize charging time while ensuring safety and capacity. The device allows for programmable charge currents ranging from 20 mA to 200 mA for the MCP73830L variant, and up to 1000 mA for the MCP73830 variant, making it suitable for various portable applications. This controller features a thermal foldback function that limits charge current based on die temperature, enhancing reliability during high-power conditions. It operates over an ambient temperature range of -40°C to +85°C and is packaged in a compact 6-lead TDFN (2x2 mm) format. Additional features include automatic end-of-charge control, undervoltage lockout, and a soft start function to prevent inrush current. The MCP73830T-2AAI/MYY is suitable for applications such as Bluetooth headsets, portable media players, and rechargeable gaming controllers.
