MONOLITHIC POWER SYSTEMS (MPS) MP2796DFP-0002-T Battery Monitor, Multi-Chemistry, 16 Cell, SPI, CRC Disabled, 18 to 75.2 V, -40° to 85° C, TQFP-48

MP2796DFP-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 or SPI communication. It supports connections for 7-cell to 16-cell series battery packs, with an absolute voltage exceeding 80V on particular pins. The MP2796 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. When paired with an MPF4279x fuel gauge, the MP2796 can achieve a state-of-charge (SOC) error to within 2%. Application includes E-Bikes, E-Scooters, battery backup and UPSs, power and gardening tools, energy storage systems (ESSs).

• Total cell measurement error is ±10mV max (VCELL = 2V to 4.5V, TA = 25°C)
• Supports MOSFET soft-start discharge control to eliminate pre-charge circuit
• Drives up to 100A DC with parallel N channel MOSFETs
• Charge/discharge OCP and SCP, cell UVP and OVP, pack UVP and OVP
• Cell low-/high-temperature protection, die high-temperature protection
