Battery charger management devices for single-cell Li-ion or Li-polymer batteries

Monolithic Power Systems MP2733 Battery Charger Management Devices, available now from Mouser, are highly integrated switchmode battery charger management devices for single-cell Li-ion or Li-polymer batteries. These devices work with Narrow Voltage DC system power path management. The devices provide a low-impedance power path that optimises efficiency, lowers battery charging time, and extends battery life. These devices support various input sources, including standard USB host ports and high-powered wall adapters with fast-charge capabilities. The I2C interface permits the device to be flexibly controlled with configurable charging and system settings.

The devices initiate and complete a charging cycle with no software control. It automatically detects the battery voltage and charges the battery in different stages. Charging automatically ends when a full charge is detected. When the charged battery drops under the recharge threshold, the charger automatically starts another charging cycle. These devices offer various safety features for battery charging and system operations, including a charging safety timer, battery temperature monitoring, OVP, and OCP.

Typical applications include tablets, smartphones, wireless cameras, and other portable devices.
