EV2797-0000-FP-00A Evaluation Kit 7-Cell to 16-Cell, High-Accuracy I2C Battery Monitoring and Protection System Evaluation Board
The EV2797-0000-FP-00A evaluation board is designed to demonstrate the capabilities of the MP2797DFP-0000, 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-0000 supports I2C 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 EV2797-0000-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.
