MONOLITHIC POWER SYSTEMS (MPS) MP2797DFP-0002-T Battery Monitor, Multi-Chemistry, 16 Cell, SPI, CRC Disabled, 18 to 75.2 V, -40° to 85° C, TQFP-48

MP2797DFP-0002-T is a robust battery management device, providing a complete analogue front-end (AFE) monitoring and protection solution. It is designed for multiple-cell series battery management systems (BMS). The device can support I²C communication. It 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 analogue-to-digital converters (ADCs). The first ADC measures each channel�s differential cell voltages (up to 16 channels), die temperature, and 4-channel temperatures via external NTC thermistors. The second ADC measures the charge/discharge current via an external current sense resistor. The dual ADC architecture enables synchronous voltage and current measurements for cell and pack impedance monitoring. Application includes energy storage system, E-Bikes, E-Scooters, light electric vehicles, power and gardening tools, battery backups and UPS.
