The EV2791-0000-FP-00A is an evaluation board designed to demonstrate the capabilities of the MP2791, a robust battery management device. The MP2791 provides a complete solution that can monitor the analog front-end (AFE) and provide protections. It is designed for battery systems with multiple cells in series. The MP2791DFP-0000 supports I²C communication.

The MP2791 supports connections for 7-cell to 14-cell series battery packs, with absolute voltages exceeding 75V on some pins. The device integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel’s differential cell voltage (up to 14 channels), die temperature, and 4-channel battery temperature via an external negative temperature coefficient (NTC) thermistor. The second ADC measures the charge and discharge currents via an external sense resistor.

The MP2791 provides high-side MOSFET (HS-FET) drivers and many robust protections. Full protection features include over-current protection (OCP), short-circuit protection (SCP), battery under-voltage protection (UVP), battery over-voltage protection (OVP), and high-temperature/low-temperature protection. All of the protections have configurable thresholds.

The EV2791-0000-FP-00A includes external balancing FETs that equalize mismatched cells. The MP2791 also has integrated balancing FETs for internal cell balancing, as well as optimized baseline current consumption that depends on the operating mode.

The MP2791 is available in a TQFP-48 (7mmx7mm) package.
