EV2796-0000-FP-00A

The EV2796-0000-FP-00A and EV2796-0002-FP-00A are evaluation boards designed to demonstrate the capabilities of the MP2796, a complete analog front-end (AFE) monitoring and protection IC. The MP2796 supports 7-cell to 16-cell series battery packs with outstanding current and voltage measurement accuracy and a complete set of protection features. The MP2796 measures each cell’s voltage and includes high-side MOSFETs (HS-FETs) for charge and discharge control. It measures the die temperature and cell temperature via 4 negative temperature coefficient (NTC) thermistor inputs. The MP2796 contains internal passive-balancing MOSFETs capable of driving up to 58mA, and can also drive external balancing transistors for higher currents. The discharge (DSG) MOSFET includes a configurable soft start (SS) that provides a controlled start-up, eliminating the need for an external pre-charge circuit. The MOSFETs 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. These evaluation boards combine the MP2796 with power MOSFETs and a current-sense resistor to support up to 70A of charge/discharge current. If needed, the EV2796-0000-00A and EV2796-0002-FP-00A include placeholders to add external MOSFETs for a higher balancing current. The EV2796-0000-00A works with the MP2796DFP-0000 and supports I2C communication, while the EV2796-0002-FP-00A works with the MP2796DFP-0002 and supports SPI communication.
