The EV2787-0000-FP-00A and EV2787-0002-FP-00A evaluation boards are designed to evaluate the MP2787, a complete analog front-end (AFE) monitoring IC. The MP2787 supports 7-cell to 16-cell series battery packs with outstanding measurement accuracy.

The MP2787 measures each cell’s voltage, while also synchronously measuring charge/discharge current and Coulomb counting via an external current-sense resistor. It also measures die temperature and cell temperature via four NTC thermistor inputs. The MP2787 contains internal passive balancing MOSFETs capable of driving up to 58mA, and is capable of driving external balancing transistors for higher current.

The MP2787 features robust hardware monitoring alarm functions, such as over-current (OC) interrupt, battery under-voltage (UV) interrupt, battery over-voltage (OV) interrupt, and high-/low-temperature interrupt. All of these interrupts have configurable thresholds.

These evaluation boards work with the MP2787 and a current-sense resistor to support up to 70A of charge/discharge current. The board also includes placeholders to add external transistors for a higher balancing current, if needed.

The EV2787-0000/0002-FP-00A can be evaluated by connecting to an 18V to 75.2V battery pack (or simulated battery pack). These evaluation boards require a computer with an available USB port and the MPS evaluation software installed. An MPS USB-to-I²C/SPI communication interface allows the PC to interface to the MP2787 communication port.

The EV2787-0000-FP-00A works with the MP2787DFP-0000 and supports I²C communication, while the EV2787-0002-FP-00A works with the MP2787DFP-0002 and supports SPI communication.

The MP2787 is available in a TQFP-48 (7mmx7mm) package.
