MP2723AGQC

The MP2723A is a 3A, highly integrated, switch-mode battery charge management device for single-cell Li-ion and Li-polymer batteries. The device supports narrow-voltage DC (NVDC) 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. The I2C serial interface allows the MP2723A to be flexibly controlled via the adjustable charging and system settings. The device 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 and DM pins. It supports USB On-the-Go (OTG) operation by supplying 5V on the input bus with an output current (IOUT) limit of up to 1.5A. The MP2723A can initiate and complete charging cycles without software control. The device automatically detects the battery voltage and charges the battery in different stages. The charger automatically terminates once 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). If a fault occurs, the charger asserts INT to the host. The device provides disabled battery FET (BATFET) control to enter shipping mode, as well as system reset functions via the DISC pin. The MP2723A is available in a QFN-26 (3.5mmx3.5mm) package.
