The MCP73861-I/ML from Microchip Technology is a highly advanced linear charge management controller suitable for space-limited and cost-sensitive applications. It integrates essential features for efficient battery charging, including constant voltage and current regulation, cell preconditioning, and automatic charge termination.
This device provides a preset voltage regulation of +0.5% accuracy, with selectable options including 4.1V and 4.2V for single-cell Li-Ion/Li-Polymer batteries. The charge current is programmable up to a maximum of 1.2A. It operates within a temperature range of -40°C to +85°C and is available in a 16-pin QFN package.
Key features include integrated pass transistor, current sense, reverse-blocking protection, programmable safety timers, and charge status/fault outputs for direct LED drive. The MCP73861-I/ML simplifies battery charger designs by requiring a minimum number of external components, making it ideal for applications such as PDAs, cellular telephones, and hand-held instruments.
