EV2795-0000-FP-00A

The EV2795-0000-FP-00A evaluation board is designed to demonstrate the capabilities of the MP2795, a complete analog front-end (AFE) monitoring and protection IC. The MP2795 supports 7-cell to 16-cell series battery packs with outstanding voltage and current measurement accuracy and a complete set of protection features.

The MP2795 measures each cell’s voltage, while also synchronously measuring the charge/discharge current and Coulomb counting via an external current-sense resistor. The MP2795 includes high-side MOSFET (HS-FET) drivers for charge and discharge control. It measures the die temperature and cell temperature via 4 NTC thermistor inputs. The MP2795 contains internal passive balancing MOSFETs capable of driving up to 58mA, and it can drive external balancing transistors for a higher current.

The discharge (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 MOSFET drivers also incorporate over-current protection (OCP), short-circuit protection (SCP), battery under-voltage protection (UVP), battery over-voltage protection (OVP), and high-/low-temperature protection. All of these protections have configurable thresholds.

The EV2795-0000-FP-00A combines the MP2795 with power MOSFETs and a current-sense resistor to support up to 70A of charge/discharge current. If needed, the board also includes placeholders to add external MOSFETs for a higher balancing current.
