The MBMxxS-P100-x is a complete solution design for the BMUxxS-P100-x, a board for high-current designs with a 7-cell to 16-cell series battery management unit. This board uses the MP279x ICs, a robust family of battery management analog front-ends (AFEs) that provide a complete AFE monitoring and protection solution. The MP279x supports up to 16 cells in series, and provides two separate analog-to-digital converters (ADCs) for synchronous voltage and current measurements.

The high-side MOSFET (HS-FET) driver and robust hardware (HW) protection functions come with configurable thresholds. Protections include over-current protection (OCP), short-circuit protection (SCP), battery and cell over-voltage protection (OVP), battery and cell under-voltage protection (UVP), over-temperature protection (OTP), and under-temperature protection (UTP). The MP279x also integrates internal balancing FETs to equalize mismatched cells, while offering the option to control external FETs for a higher balancing current.

The board also features the MPF4279x, a standalone battery fuel gauge IC that performs state-of-charge (SoC), time-to-full, time-to-empty, and unavailable energy estimation using a custom battery model obtained through exhaustive characterization and voltage, current, and temperature readings. This solution is fast, simple, and easy to configure through the graphic user interface (GUI).

The board offers a high-power solution with up to 100A of constant current and up to 150A of peak current. Each board offers a different combination of the MP279x and MPF4279x.
