Features

The EVM supports the following features:

  • EVM for the low-voltage features of the LM2105 gate driver
  • 5-V to 18-V VCC power supply range
  • TTL and CMOS compatible inputs
  • PCB layout optimized for bias supply bypassing cap, gate-drive resistance selection
  • Capacitive load, external gate drive resistor and diode for gate drive network evaluation
  • Allows quick verification of most of the data sheet parameters
  • Test points allow probing all the key pins of the LM2105
