The EV2790-0000-FP-00B is an evaluation board designed to demonstrate the capabilities of the MP2790, a robust battery management device. The MP2790 provides a complete analog front-end (AFE) monitoring and protection solution. It is designed for multiple-cell series battery management systems (BMS). The device supports I²C communication.

The MP2790 supports connections for 4-cell to 10-cell series battery packs, with an absolute voltage exceeding 80V on particular pins. The device integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel’s differential cell voltage (up to 10 channels), die temperature, and 4-channel temperatures via external negative temperature coefficient (NTC) thermistors. The second ADC measures the charge and discharge current via an external current-sense resistor. The dual ADC architecture enables synchronous voltage and current measurements for cell and pack impedance monitoring.

The MP2790 includes high-side MOSFET (HS-FET) drivers for independent charge (CHG) and discharge (DSG) control. The DSG MOSFET driver includes a configurable soft start (SS) that provides a controlled turn-on, eliminating the need for an external pre-charge circuit. The DSG MOSFET driver also incorporates protections such as reporting discharging over-current (DOC), short-circuit, battery under-voltage (UV), over-temperature (OT), and under-temperature (UT) faults. The CHG MOSFET drivers incorporate protections such as reporting charging over-current (COC), short-circuit, battery over-voltage (OV), OT, and UT faults. All of these protections have configurable thresholds.

Internal passive balancing MOSFETs can be used to equalize mismatched cells, supporting up to 58mA. The MP2790 provides the option to drive external balancing transistors (MOSFET or BJT).

The MP2790 has optimized baseline current consumption dependent on the mode. It is available in a TQFP-48 (7mmx7mm) package.
