I²C-Controlled, Single-Cell Switching Charger with Power-Path Management and 3.6A Boost Output

The MP2696A is a highly integrated, flexible, switch-mode battery-charging, power-path management device designed for a single-cell Li-ion and Li-polymer battery to be used in a wide range of portable applications.

The MP2696A integrates three battery-charging phases: pre-charge, constant-current, and constant-voltage charge. This device also manages the input power source through input current limit regulation and minimum input voltage regulation.

The MP2696A can switch to boost mode to generate the system power output from the battery.

The MP2696A has an integrated IN to SYS pass-through path to pass the input voltage to the system.

Using an I²C interface, the host can flexibly program the charge and boost parameters. The device operating status can also be read in the registers.

Safety features include SYS short-circuit protection, input over-voltage protection, battery under-voltage protection, thermal shutdown, and JEITA battery temperature monitoring.  

The MP2696A is available in a QFN-21 (3mmx3mm) package.

The MP2696A is highly customizable. Users can configure the MP2696A via the downloadable I2C GUI.

This I2C GUI allows you to program the MP2696A. By using this I2C GUI, you can set the output voltage, PG delay enable, output current limit, and more. Please reference the user guides for installation and programing instructions.

MP2696A Evaluation Board

The EV2696A-Q-00B is an evaluation board for the MP2696A, a high-integrated, flexible switch-mode battery charge management and system power path management device.

The MP2696A has three operation modes: charge mode, boost mode and sleep mode.

In charge mode, EV2696A-Q-00B achieves up to 3.6A charge current with a 5V input source.

In boost mode, EV2696A-Q-00B achieves up to 6.5A peak inductor current to deliver a 5V SYS output.

All the parameters and control can be easily accessed via the I2C interface.
