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 MAXREFDES1289 reference design evaluates the MAX17852/MAX17853 for 400V four-wheeler Battery Management Systems (BMS).

This design showcases capabilities of the MAX17852/ MAX17853, like individual 14-cell voltage measurements, pack-voltage, temperature (up to four sensors using General Purpose Inputs/Outputs (GPIOs)), pack-current measurement (MAX17852 only), and passive cell balancing.

The MAX17852/MAX17853 support ASIL-D requirements for cell voltage, temperature, current, communication, and Failure-Mode Effects Analysis (FMEA).

特征

  • Up to 112 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/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 (UV), 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.
