Description

The MP2698 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 for use in a wide range of portable applications.

The IC uses two operating modes, charge mode and boost mode, to manage system and battery power based on the state of the input and output.

When input power is present, the MP2698 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 MP2698 switches to boost mode to power SYS from the battery. The IC supports BC1.2 output by identifying the request through DP2/DM2.

To guarantee safe operation, the IC includes input over-voltage protection (OVP), battery over-voltage protection (OVP), thermal shutdown, battery temperature monitoring, and a programmable timer to prevent the prolonged charging of an abnormal battery.

With the I²C interface, the IC can flexibly program the charging and boosting parameters, such as input current limit, charging current, battery regulation (charge-full) voltage, safety timer, boost output current limit, and so on. The IC can also provide the operation status through the I²C registers and battery status via four LEDs.

The MP2698 is available in a QFN-28 (4mmx4mm) package.
