MP2673GR-xxxx-P

The MP2673 is a highly integrated, flexible, switch-mode, battery charge management and system power-path management device designed for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. The IC has two operating modes (charge mode and boost mode) to allow for management of the system and battery power based on the state of the input and output. When input power is present (up to 14V), the device operates in charge mode. The device detects the battery voltage automatically and charges the battery in four phases: trickle current charge, pre-charge, constant-current charge, and constant-voltage charge. In the absence of an input source, the MP2673 switches to boost mode to power SYS from the battery. The IC can provide a wide boost voltage to SYS by adjusting the feedback voltage at FB. With the I2C interface, the IC can flexibly program charging and boosting parameters such as input current limit, charging current, battery regulation (charge full) voltage, safety timer, boost output current limit, etc. The MP2673 can also provide the operation status through the I2C registers and remaining battery capacity via four LEDs. To guarantee safe operation, the IC limits the die temperature to a preset value of 120°C (default). Other safety features include input over-voltage protection (OVP), battery over-voltage protection (OVP), thermal shutdown, and battery temperature monitoring. The MP2673 is available in a QFN-28 (4mmx4mm) package.
