MP2723A 2 3A, I C-Controlled SW Charger with NVDC Power Path, USB OTG, and Enhanced ADC DESCRIPTION FEATURES The MP2723A is a 3A, highly integrated, switch- 3.7V to 5.5V Operating Input Voltage Range mode battery charge management device for Up to 22V Sustainable Voltage single-cell Li-ion or Li-polymer batteries. This High-Efficiency, 3A, 1.35MHz Buck device works with narrow-voltage DC (NVDC) Charger: system power path management, and is suitable o Up to 92% Charge Efficiency at 3A for a variety of applications, such as Charge Current smartphones, tablets, wireless cameras, and o Auto-Detection for USB SDP, CDP, other portable devices. Its low-impedance power DCP, and Non-Standard Adapters path optimizes efficiency, reduces battery USB OTG with 4.8V to 5.5V Adjustable 2 charging time, and extends battery life. The I C Output: Up to 1.5A Output with Up to 93% serial interface allows the device to be flexibly Efficiency controlled via adjustable charging and system NVDC Power Path Management: settings. o Instant On Works with No Battery or Deeply Discharged Battery The MP2723A supports 5V input sources, o Ideal Diode Operation in Battery including standard USB host ports, USB Supplement Mode charging ports, and USB-compliant wall High Battery Discharge Efficiency with adapters. The device provides USB input type 14m BATFET up to 8.5A detection via the DP/DM pins. It supports USB 2 I C Port for Flexible System Parameter On-the-Go (OTG) operation by supplying 5V on the input bus with an output current limit up to Setting and Status Reporting 1.5A. Fully Integrated Power MOSFETs and Current Sensing The MP2723A also initiates and completes Dedicated DISC Pin to Control Ship Mode charging cycles without software control. The and System Reset device automatically detects the battery voltage 13A Low Battery Leakage Current in and charges the battery in different stages. The Shipping Mode charger automatically terminates when it detects Integrated ADC for Monitoring Input that the battery is fully charged. If the battery Voltage, Input Current, Battery Voltage, drops below its recharge threshold, the charger Charge Current, System Voltage, and initiates another charging cycle. Battery Temperature The charger provides various safety features for Charging Status Indicator battery charging and system operations, Safety Features: Configurable JEITA for including a charging safety timer, battery Battery Temperature Protection, Battery temperature monitoring, over-voltage protection Charging Safety Timer, Thermal Regulation (OVP), and over-current protection (OCP). If a 2 and Shutdown, Watchdog Monitoring I C fault occurs, the charger asserts INT to the host. Operation, and Input/System OVP The device provides disabled battery FET (BATFET) control to enter shipping mode, as APPLICATIONS well as system reset functionality via the DISC Tablet PCs pin. Smartphones The MP2723A is available in a QFN-26 Wireless Cameras (3.5mmx3.5mm) package. Other Portable Devices All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
