This reference board showcases an air-cooled high current protection switch (up to 300A) for automotive 48V batteries. It utilizes a 2-channel MOSFET gate driver (2ED4820-EM) to control Power MOSFETs for battery connection. Current monitoring and overcurrent protection are enhanced with shunt and hall-based sensing (TLE4972-AE35D5). Controlled by an XMC4700 microcontroller kit, the board supports configuration via a command-line interface.

Features

  • 48V for continuous currents 300A
  • High-side O/P channels in common source
  • Pre-charge path for DC-Link capacitors
  • Passive freewheeling (active freewheeling optional)
  • Shunt based monitoring on low-side
  • Hall current monitoring on high-side
  • Over-current protection with programmable thresholds
  • Extensive diagnostics
