The MCP73828-4.2VUA from Microchip Technology is a linear charge management controller designed for space-limited, cost-sensitive applications requiring single-cell Lithium-Ion battery charging.
This IC integrates constant voltage and controlled current regulation, along with automatic cell preconditioning for deeply depleted cells and continuous temperature monitoring. It provides a charge complete output for LED or microcontroller interface and automatically powers down when input power is removed. The device operates within a temperature range of -20°C to +85°C.
The MCP73828-4.2VUA charges batteries in three phases: preconditioning, controlled current, and constant voltage. The charge current is programmable via an external sense resistor, offering design flexibility. The voltage regulation accuracy is within ±1% over the operating temperature and supply voltage range. This specific variant is preset to a regulation voltage of 4.2V.
Packaged in an 8-pin MSOP, the MCP73828-4.2VUA is suitable for surface mount applications. Its typical applications include single-cell Lithium-Ion battery chargers for personal data assistants, cellular telephones, hand-held instruments, cradle chargers, and digital cameras.
