NXP Semiconductors RD33774PC3EVB Evaluation Board

NXP Semiconductors RD33774PC3EVB Evaluation Board is a centralized Cell Monitoring Unit (CMU) reference design with electrical Transport Protocol Link (ETPL) communication. This evaluation board implements three MC33774ATP battery-cell controller ICs that monitor up to 18 cells. The RD33774PC3EVB evaluation board uses no capacitive isolation for offboard communication. This evaluation board consists of the HVBMS Battery Management Unit (BMU) and the 800V HVBMS Battery Junction Box (BJB). Typical applications include automotive and industrial devices.

Features

  • Three MC33774ATP battery-cell controller ICs that monitor up to 18 cells
  • Capacitive isolation for onboard communication
  • Cell Electrostatic Discharge (ESD) capacitors package 0805
  • Placeholder for I2C-bus EEPROM
  • Four-layer board, all components are assembled only on the top side
  • All eight external thermistor inputs are available
  • Three 1206 Surface-Mounted Device (SMD) resistors per balancing channel for individual cell-voltage balancing

Applications

  • Automotive
    • Battery Management System (BMS)
  • Industrial devices
