Monolithic Power Systems (MPS) EV2651-VT-00A Evaluation Board demonstrates the MP2651 buck-boost charger IC designed for battery packs with one cell to four cells in series. The EV2651-VT-00A Evaluation Board charges the battery with a maximum 6A charge current. When source mode is facilitated, the device has an output current (IOUT) limit up to 6A. With the I2C/SMBus interface, the MP2651 can flexibly configure the charge and discharge parameters. The I2C interface can also supply the device and fault statuses through the registers.
