Product overview
Description
The 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 evaluation EVAL-L9963-MCU is recommended. EVAL-L9963 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 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.
