The MCP73853/55 is a high-efficiency charging management controller designed for USB-compatible applications. It integrates a charge pump, current sensing, reverse blocking protection, and temperature monitoring. The MCP73853 uses a 16-pin 4x4mm QFN package, while the MCP73855 uses a 10-pin 3x3mm DFN package. Both support USB power standards and offer configurable voltage thresholds (4.1V or 4.2V) for various battery types. The devices operate from 4.5V to 5.5V input and function over a temperature range of -40°C to +85°C.
The datasheet provides detailed DC and AC electrical characteristics, including voltage regulation accuracy, current limits, thermal shutdown, and timing parameters. It also includes application circuit diagrams and typical performance curves for voltage regulation and current control under various conditions. This manual is written in Chinese.
