Product Overview

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. 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 analogue input for temperature sensing (plus an additional on-board NTC to sense PCB temperature). The board provides an on-board microcontroller with preloaded GUI (graphical user interface) firmware intended to be used with STSW-L9963E PC GUI.
  • Measures from 4 to 14 cells in series, with 0 µs desynchronization delay between samples
  • Coulomb counter supporting pack overcurrent detection in both ignition on and off states
  • Fully synchronized current and voltage samples
  • 16-bit voltage measurement
  • 2.66Mbps isolated serial communication with regenerative buffer, supporting dual access ring
  • Transformer based isolation
  • Up to 4 analogue inputs for NTC sensing, plus PCB temperature sensing
  • On-board microcontroller SPC574S64E3 with 32-bit power architecture MCU
  • On-board L9001 regulator as microcontroller power supply
  • Hot plug dedicated circuit
