Monolithic Power Systems MP2723A
The MP2723A is a 3A, highly integrated, switchmode battery charge management device for single-cell Li-ion or Li-polymer batteries. This device works with narrow-voltage DC (NVDC) system power path management, and is suitable for a variety of applications, such as smartphones, tablets, wireless cameras, and other portable devices. Its low-impedance power path optimizes efficiency, reduces battery charging time, and extends battery life.

DESCRIPTION
The I2C serial interface allows the device to be flexibly controlled via adjustable charging and system settings. The MP2723A supports 5V input sources, including standard USB host ports, USB charging ports, and USB-compliant wall adapters. The device provides USB input type detection via the DP/DM pins. It supports USB On-the-Go (OTG) operation by supplying 5V on the input bus with an output current limit up to 1.5A. The MP2723A also initiates and completes charging cycles without software control. The device automatically detects the battery voltage and charges the battery in different stages. The charger automatically terminates when it detects that the battery is fully charged. If the battery drops below its recharge threshold, the charger initiates another charging cycle. The charger provides various safety features for battery charging and system operations, including a charging safety timer, battery temperature monitoring, over-voltage protection (OVP), and over-current protection (OCP).
