MP2710GC

The MP2710 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with system power-path management (PPM) for space-restricted, portable applications. The MP2710 takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously. The charger features pre-charge (PRE.C), fast current (CC), and constant voltage (CV) regulation, as well as charge termination and auto-recharge. The PPM function ensures continuous power to the system by automatically selecting the input, battery, or both to power the system. This function features a low-dropout (LDO) regulator from the input to the system and a 100mΩ switch from the battery to the system. PPM separates the charge current (ICHG) from the system load, which allows for proper charge termination and keeps the battery in full-charge mode. The MP2710 provides system short-circuit protection (SCP) by limiting the current from the input to the system and the battery to the system. This feature is especially critical for preventing the Li-ion battery from being damaged due to an exceedingly high current. On-chip battery under-voltage lockout (UVLO) cuts off the path between the battery and the system if the battery voltage (VBATT) drops below the configurable battery UVLO threshold. This prevents the Li-ion battery from being over-discharged. An integrated I2C control interface allows the MP2710 to configure the charging parameters, such as the input current limit (IIN_LIMIT), minimum input voltage regulation (VIN_MIN), ICHG, battery regulation voltage, safety timer, and battery UVLO. The MP2710 is available in a WLCSP-9 (1.85mmx1.85mm) package.
