The EVAL-L9963E-MCU is a hardware tool for evaluation of L9963E, automotive chip for battery management applications. It can be used for the development of a 48 V battery management system (BMS) or as lower stage of a distributed BMS (depending on total battery voltage. Additional stages can be added thanks to EVAL-L9963E-NDS).
EVAL-L9963E-MCU allows the user to connect up to 14 channels for cell voltage sensing, one channel for current sensing, and up to 4 analog input for temperature sensing (plus an additional on-board NTC to sense PCB temperature). The board provides an onboard microcontroller with preloaded GUI (graphical user interface) firmware intended to be used with STSW-L9963E PC GUI.
