Features• Pin connector for external MCU for FW development• Measures from 4 to 14 cells in series, with 0 us desynchronization delay
between samples. Supports also busbar connection without altering cell results• Coulomb counter supporting pack overcurrent detection in both ignition on and
off states• Fully synchronized current and voltage samples• 16-bit voltage measurement• 2.66 Mbps isolated serial communication with regenerative buffer, supporting
dual access ring• Transformer based isolation• Up to 4 analog inputs for NTC sensing, plus PCB temperature sensing• Onboard L9001 regulator power supply.
DescriptionThe EVAL-L9963 is a hardware tool for evaluation of L9963, 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-L9963-NDS).
An external MCU is necessary for development purpose. For L9963 evaluationEVAL-L9963-MCU is recommended. EVAL-L9963 allows the user to connect up to 14channels for cell voltage sensing, one channel for current sensing, and up to 4analog input for temperature sensing (plus an additional on-board NTC to sense PCBtemperature). The board provides pin connector with relevant control signal (i.e. SPI)in order to help prototyping of a BMS based on EVAL-L9963 and an external MCU.
