MP2718A

The MP2718A is a highly integrated, 2.5A, switch-mode battery management device for single-cell Li-ion or Li-polymer batteries. The device employs a low-impedance narrow-voltage DC (NVDC) power path management structure, which optimizes the charging efficiency, reduces the battery charging time, and extends the battery life. The battery leakage current in shipping mode can reach down to 1μA, which extends the device shelf life as much as possible. The MP2718A supports down to 10mA of termination current, making it well-suited for small-capacity battery applications. The MP2718A supports On-The-Go (OTG) mode to supply a 5V output from the battery. The IN pin or PMID pin can be set as the OTG output terminal. If IN is set as the boost output, the block MOSFET is turned on in OTG mode. If PMID is set as the boost output terminal, the block MOSFET remains off in OTG mode. The device also offers a PMID_OUT driver to drive an external N-channel MOSFET to disconnect the PMID output from external loads if any protection is triggered. With an I2C interface, the MP2718A offers complete operating control of the charge and discharge parameters, such as the input current limit (IIN_LIM), input voltage limit (VIN_LIM), charge current, battery-full regulation voltage, output voltage (VOTG), and output current (IOTG) in boost mode. It can also provide status/interrupt monitoring via the I2C interface. To guarantee safe operation, the device provides various safety features for battery charging and system operations, including input over-voltage protection (OVP), battery OVP, system OVP, thermal shutdown, a charging safety timer, and a fully customizable JEITA profile with configurable temperature windows and actions. The MP2718A is available in a QFN-20 (3mmx3mm) package.
