The MCP73831/2 devices are advanced charge management controllers designed for space-limited and cost-sensitive applications. They come in small packages such as 8-Lead, 2 mm x 3 mm DFN or 5-Lead SOT-23, making them suitable for portable devices. These devices comply with the specifications for USB charging when connected to a USB port.
The MCP73831/2 controllers use a constant-current/constant-voltage charging algorithm with selectable preconditioning and charge termination. The constant voltage regulation can be set to 4.20V, 4.35V, 4.40V, or 4.50V to accommodate different battery charging requirements. The constant current value is determined by an external resistor. To ensure device reliability, the controllers limit the charge current based on temperature during high-power or high-ambient conditions.
Various options are available for preconditioning threshold, preconditioning current value, charge termination value, and automatic recharge threshold. Preconditioning can be enabled or disabled, and the values for preconditioning and charge termination can be set as a ratio or percentage of the programmed constant current value. The electrical characteristics and standard options are provided in the documentation.
The MCP73831/2 devices are fully specified for operation in a temperature range of -40°C to +85°C.
