MCP73831 Li-ion Battery Charger SMD IC (SOT-23 Package)
The MCP73831 is a compact, highly integrated Li-ion battery charger SMD IC available in a SOT-23 package, designed for efficient and straightforward charging solutions. This IC is tailored for charging single-cell lithium-ion or lithium-polymer batteries and features a linear charging algorithm to ensure safe and efficient battery management. It is widely used in portable devices due to its small footprint and minimal external component requirements. The MCP73831 offers a reliable, constant current/constant voltage (CC/CV) charging profile, optimizing charging performance and battery longevity. It supports charging currents up to 500 mA, adjustable via an external resistor. Key safety features include thermal regulation, which reduces the charge current when the die temperature rises above a specific threshold, preventing overheating and protecting both the IC and the battery. This charger IC has a low-dropout voltage, making it effective for low-input voltage conditions, and it supports automatic termination once the battery reaches full capacity. The status output pin indicates charging status, facilitating integration with indicator LEDs or microcontroller monitoring systems.
