MAXREFDES1277: 48V Data-Acquisition System with Integrated Current Sense Amplifier for Two-Wheeler Battery Management Applications

参考设计免责声明 参照  重要声明和免责声明  涵盖参考设计和其他Maxim资源

描述

The MAXREFDES1277 reference design enables quick evaluation of the MAX17852/53 for 48V two-Wheeler battery management applications (BMS).

This design showcases capabilities of the MAX17852/53 like individual 14-cell voltage measurements, pack voltage, temperature (up to four sensors using general purpose inputs/outputs [GPIOs]), pack current (MAX17852 only) measurement, and passive cell balancing.

The MAX17852/53 supports ASIL-D requirements for cell voltage, temperature, current, communication, and failure mode effects analysis (FMEA).

特征

  • 3 to 14 cell voltage measurement with ±2mV accuracy at 5°C to 40°C
  • Supports flexi pack configuration
  • Pack current measurement using external current sense resistor
  • Passive cell balancing up to 300mA with internal switch with odd or even cell balancing scheme (single cell or group)
    • Auto cell balancing configuration with undervoltage (UV) threshold and timer options
    • Manual cell balancing configuration
  • Four configurable auxiliary inputs for temperature, voltage, or GPIO
  • Internal die temperature measurement
  • Individually configurable safety alert
    • Overvoltage (OV), undervoltage, overtemperature and undertemperature faults
    • One cell-mismatch alert
  • Selectable universal asynchronous receiver- transmitter (UART) or serial peripheral interface (SPI)
  • UART configurations with packet error checking (PEC)
    • Dual UART configuration with redundancy
    • Single UART configuration
  • Single-side component placement
  • Compatible with MAX17852EVKIT software along with MINIQUSB board
