2.4 Features

The LMG342XEVM-04X has the following features and specifications:

  • Overtemperature, overcurrent, short-circuit, and undervoltage lockout protection with FAULT and OC indication that is level-shifted to an AGND referenced signal

  • A real-time digital output with its duty cycle indicating the device's junction temperature

  • Cycle-by-cycle overcurrent protection and latched short-circuit protection

  • Gate logic input support of either 3.3-V or 5-V logic
  • Maximum recommended operating voltage of 480-V and absolute maximum voltage of 600-V

The mother boards have the following features and specifications:

  • Requires only a single 12-V bias supply
  • Requires only a single 0-V to 5-V PWM input to generate a gate drive signal
  • PWM disables in the event of a fault from the LMG342XEVM-04X
  • Maximum recommended operating voltage of 480-V and absolute maximum voltage of 600-V
