Monolithic Power Systems (MPS) MP2791 Battery Monitors & Protectors

Monolithic Power Systems (MPS) MP2791 Battery Monitors and Protectors are a robust battery management device that provides a complete Analog Front-End (AFE) monitoring and protection solution. These devices are designed for multiple-cell series Battery Management Systems (BMS) and can support I2C or SPI communication. The MP2791 battery monitors and protectors include High-Side MOSFET (HS-FET) drivers for charge and discharge control.

Features

    • <±2% State-of-Charge (SOC) error with MPF4279x fuel gauge
    • <5mV cell voltage measurement error
    • <±0.5% current/coulomb counter error
    • Strictly synchronized current/voltage measurement for impedance sensing
  • Includes high-side N-channel MOSFET drivers for charge and discharge control:
    • Supports MOSFET soft-start discharge control to eliminate pre-charge circuit
    • Drives up to 100A DC with parallel N-channel MOSFETs
  • Hardware configurable protections:
    • Charge/discharge OCP and SCP
    • Cell UVP and OVP
    • Pack UVP and OVP
    • Cell low-/high-temperature protection
    • Die high-temperature protection
  • Passive cell-balancing up to 58mA per cell:
