The MCP73853 is a linear charge management controller designed for USB-compatible Li-Ion and Li-Polymer battery charging applications. It features integrated components such as a pass transistor, current sensing, and reverse blocking protection, which contribute to a compact design suitable for space-limited applications. The device offers high-accuracy voltage regulation with two selectable options of 4.1V and 4.2V, and supports programmable charge current settings. Key functionalities include programmable safety charge timers, automatic end-of-charge control, and preconditioning for deeply depleted cells. The MCP73853 also includes a charge status output and a fault output for direct LED drive, along with optional continuous cell temperature monitoring. It operates over a temperature range of -40¬8C to +85¬8C and is packaged in a 16-lead, 4x4 mm QFN format. This product is particularly suitable for applications such as personal data assistants, cellular phones, and digital cameras, making it a versatile choice for engineers looking for reliable battery management solutions.
The MCP73853 is a highly advanced linear charge management controller for use in space limited, high-performance applications. The MCP73853 integrates most of the external components (pass transistor, reverse blocking protection, current sensing) and combines high-accuracy constant voltage, constant current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, and charge status and fault indication in a space-saving 16-pin, 4 x 4 QFN package. The MCP73853 is designed specifically for USB applications, adhering to all the specifications governing the USB power bus.
