EV2797-0002-FP-00A

The EV2797-0002-FP-00A evaluation board is designed to demonstrate the capabilities of the MP2797DFP-0002, a robust battery management device. The MP2797 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 MP2797DFP-0002 supports SPI communication. The MP2797 supports connections for 7-cell to 16-cell series battery packs, with an absolute voltage exceeding 80V on particular pins. The MP2797 integrates two separate analog-to-digital converters (ADCs). The first ADC measures each channel’s differential cell voltage (up to 16 channels), die temperature, and 4-channel battery temperature via an external negative temperature coefficient (NTC) thermistor. The second ADC measures the charge/discharge current via an external sense resistor. The MP2797 has high-side (HS) drivers and features robust protection functions, such as 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 the protections have configurable thresholds. The EV2797-0002-FP-00A has external balancing FETs to equalize mismatched cells. The MP2797 also has integrated balancing FETs for internal cell-balancing. The MP2797 has an optimized baseline current consumption that depends on the operating mode. It is available in a TQFP-48 package.
